Nokia E62

Posted by sasikumarbalasubramanian on October 14, 2007

A Web-browsing wizard and e-mail chameleon, the Nokia E62 is poised to become a top handheld when it comes to U.S. consumers later this fall. And if what I’ve been hearing about the price is correct, it should be pretty easy on the wallet as well.

Nokia E62

I spent a week with a buggy prerelease model of the E62. (Five ROM revisions passed while I was testing it, according to Nokia.) Even in its prototype state, the E62 had a tremendous amount going for it. It’s a big, flat slab that looks like a cross between an old-school BlackBerry and a Motorola Q redesigned by Saab. The 2.8-inch screen is absolutely gorgeous with a 320-by-240 resolution. Below the screen are four slightly confusing soft keys, menu and e-mail buttons, and a very usable joystick. This isn’t a touch-screen device, so you’ll be using that joystick a lot, but it’s a joy to use.
The E62’s keyboard is big, with square, rubbery, responsive keys. You’ll find a power button near the top of the handset and volume and voice-record buttons on the device’s side. Unfortunately, there’s no camera or visible memory card slot. The E62 does accept MicroSD memory cards to supplement its 90MB of internal storage, but you have to open the case and slip them under the battery. That is annoying.
The E62 runs the latest version of the Symbian operating system, version 9.1, with the Series 60 version 3 interface. If you’ve ever used a Symbian device, you’ll immediately feel the difference. The E62 is much quicker and more responsive than previous Symbian-based phones such as the Nokia 9300 and 7610. The Symbian OS is tremendously popular overseas, and it has a thriving ecosystem of third-party software. Although most of these applications were written for earlier versions of Series 60, updates for the E62 already exist.
Symbian’s flexibility shows up in the E62’s excellent e-mail, Web, and document-reading capabilities. Nokia’s own browser is the most desktop-like of any mobile Web browser I’ve used. It’s even able to handle difficult, JavaScript-laden pages such as the sidestep.com travel site. (It doesn’t support Java applets or embedded Flash, but, hey, this is a handheld.) The only thing missing is a one-column view—you almost always have to horizontal-scroll to read whole pages. Fortunately, the excellent Opera Mobile browser is also available for the E62, and it has a dandy no-scrolling mode.
The E62 comes with a POP3/IMAP e-mail program that handles attachments, but the smartphone also works with a dizzying array of push-mail software, including GoodLink, Intellisync, Visto, DataViz RoadSync for Microsoft Exchange servers, Consilient’s new push-POP/IMAP mail solution, and even BlackBerry Connect. Unbelievably, I loaded Consilient’s and GoodLink’s clients simultaneously without any problems. Consilient’s software is very basic—no attachment support or formatting—but it does push mail from POP and IMAP accounts and is very affordable ($5/month). GoodLink works much as it does on other platforms, including full integration with Microsoft Outlook e-mails, contacts, tasks, and notes.
The E62 comes with Microsoft Word, Excel, and PowerPoint viewer/editors that handle even Word tables, complex PowerPoint presentations, and multiworksheet Excel documents, although they do take a long time to open. I also managed to max out the 32MB of program memory with two e-mail clients and a 25-slide PowerPoint presentation running concurrently.

One problem that will certainly turn off some e-mail addicts: Neither GoodLink nor Consilient alert you to new messages or calendar items from the device’s home screen. BlackBerry and Intellisync do, making those solutions potentially more usable.
Battery life is always a concern when using push e-mail devices. My E62 clocked in at almost exactly 24 hours running both GoodLink continuously and Consilient intermittently. That’s on a par with what I’ve seen from Treos and Windows Mobile devices, but not as good as BlackBerrys. Talk time without GoodLink running, however, was an impressive 11 hours 12 minutes.
The E62 syncs with PCs via Nokia’s PC Suite software, a Microsoft Windows program (sorry, no Mac version) that has gotten slicker with time but still isn’t quite up to the standards of, say, Palm Desktop. PC Suite does sync contacts and calendars with Outlook and Notes and lets you convert and transfer music files onto your phone. You can also use the E62’s mass-storage mode to make the phone appear as a hard drive on your desktop, and drag and drop files. Unlike with Palm Desktop and Microsoft’s Windows Media Player, though, there’s no easy way to reformat video to play on the device’s video player, a big multimedia minus.
Of course, the E62 is also a phone, too. As a quad-band world phone with EDGE data, it gets solid reception. Both the earpiece and the speakerphone are quite loud, and sound is very sharp and clear, with a pleasing, trebly bias. The slab-like design puts the microphone quite far away from your mouth, though, letting in too much background and wind noise for my taste. Using a Bluetooth or wired headset improved transmissions—and it also got around that this big-slab phone isn’t very comfortable to hold up to your head. Speaker-independent voice dialing works over Bluetooth, but isn’t as accurate as the Voice Signal solution seen on some other phones.
The E62 supports a very wide range of Bluetooth functions, including headsets, stereo music playback, file transfer, dial-up networking, printing, and PC connectivity. Unfortunately, the prototype’s Bluetooth was pretty buggy. For example, remote-control functions didn’t work with my Plantronics Pulsar 590a headphones, and the phone had trouble pairing with a Jabra a320s Bluetooth dongle on a PC. With a Plantronics Voyager 510 headset, Bluetooth range was pretty good—rock-solid at 15 feet, just fine at 30, and staticky but usable at 45.
The E62 should stack up well against its smartphone competition. Depending on which carriers pick it up, it will go up against the BlackBerry 8700c and 8700g, Palm Treo 650 and T-Mobile MDA/Cingular 8125 as QWERTY phones on a GSM carrier. Inevitably, it’s also going to be compared with Verizon’s Motorola Q. The E62 is a far better voice phone than either the MDA or 8125. It also has a higher-res screen and a better Web browser than the Treo, and more multimedia options and available third-party software than the BlackBerry, although the BlackBerry does a better job for individuals who want to merge Exchange, POP3, and/or Yahoo! mail in one place. The Q has easier PC sync options, but the E62 will attract people who don’t want to align themselves entirely with a Microsoft ecosystem.

In short, at a compelling price (I’ve heard as low as Rs 9500 with service), the Nokia E62 could be a killer handheld.

About BlackBerry

BlackBerry Hardware

A BlackBerry can do everything that a cell phone can do, including sending text messages via SMS. It’s also an organizer, a calendar, an e-mail client, a Web browser, a two-way pager and a palm-top computer. Although it can do some of the same things a computer can, it doesn’t have to be in a WiFi hot spot to work — it uses the cell phone network as well as 802.11b WLAN. To do all this, it combines the components of a cell phone and a PDA.

Blackberry Mobile

Some BlackBerry models have the same form factor and components as a smart phone. Others look more like PDAs or palmtop computers. Specific components can vary from one model to another, but in general the visible parts of a BlackBerry are:
LCD display
QWERTY keyboard
Click wheel
On/off, escape and other keys
Headset jack
USB charger connection
Antenna (interior on some models)
Indicator light to advise users of new messages or data
From the outside of the unit, you can also see where the microphone and speaker are located as well as where to access the rechargeable lithium ion battery.

A printed circuit board connects everything inside the case, including:
Light source for the LCD screen
32-bit microprocessor
Memory (usually flash and RAM)
Bluetooth transmitter (in some models)
Wireless modem (in some models)

Unlike many earlier PDAs, which used touch screens as a user interface, the BlackBerry has a keyboard designed for use with the thumbs. This keyboard operates much like the keyboard of your computer, with one notable difference. Most computer keyboards use dome switches, and each key lies over one switch. Pressing the key activates the switch. In a BlackBerry, however, rows of dome switches lie between the rows of keys. Each key has actuators that press one or more of the switches adjacent to it.

 

The BlackBerry’s software uses a lookup table to match each letter with a specific combination of dome switches. This layout uses fewer switches, allowing a smaller keyboard.

BlackBerry smart phones have even less space for a keyboard, so each key corresponds to more than one letter. Predictive text software called SureType lets a person type normally and determines the right word as the person types. People can also use multiple taps on each key to select different letters as most people currently do to send text messages on their cell phones.

BlackBerry Software

In addition to the push technology discussed earlier, a BlackBerry requires a variety of software on the handheld unit itself and on servers and desktops. The devices are part of a network that includes handhelds, handheld software, desktop software and server software.

The BlackBerry unit uses a proprietary BlackBerry operating system and usually includes e-mail, Web browsing, instant messaging and personal information management (PIM) software. Third-party developers have created a wide variety of other programs for the BlackBerry, like games and productivity applications.

Other third-party programs are customized applications that let people get data and updates from proprietary sales, data collection and other business software. Many of these use a browser interface and e-mail messages for data retrieval. Users get an e-mail message with a link they can click to make a phone call, view data or log in to a service. SSL and TLS encryption protect information and data.

Since a BlackBerry has less memory and processing power than a computer, each of these programs has to be relatively small and efficient. Web pages have to be simple and not rely on frames or applets, and they’re most effective when they use minimal colors. BlackBerry developers use a Java development environment that lets them simulate a BlackBerry and make sure their programs are compatible.

Businesses that employ multiple BlackBerry users often use the BlackBerry Enterprise Server software to manage each BlackBerry’s connection with the corporate network. The software runs behind the corporate firewall, and pushes information to the handheld units. System administrators can also use the server-side software to update BlackBerry units wirelessly.

Individual users can run BlackBerry Desktop Redirector software on their computers, which plays the same role as the Enterprise Server but on a smaller scale. The Desktop Redirector sends information in small pieces so it doesn’t overload the person’s connection or deliver unnecessary information to the BlackBerry. The computer has to be on and running in order for the redirector to work.
