Armed with built-in Wi-Fi, Bluetooth, a slide-out QWERTY keyboard, EDGE support, and Windows Mobile 5, the nondescript T-Mobile MDA--a rebranded version of the HTC Wizard--makes for an enticing addition to T-Mobile's staid lineup of long-in-the-tooth handhelds. As one of CNET's editors put it, it's like a Sidekick for grown-ups. Indeed, this unassuming-looking phone makes it easy to jump on to available hot spots, manage your messages, open and edit Office documents, and crank your tunes. Unfortunately, the MDA ($399) is without any new tricks or spectacular performance, and since it's hobbled by a subpar keypad and an iffy camera, it will have to fight against heavyweights such as the Palm Treo 700w, the , and the Cingular 8125 for attention. The T-Mobile MDA will be available starting February 20 with a price tag of $399.99, but you should be able to get it for less with service. The boxy, silver and black T-Mobile MDA looks like a typical PDA: The front is dominated by a roomy 2.9-inch-diagonal display, while a small T-Mobile logo and a set of navigational keys sit just beneath. Measuring 4.3 by 2.3 by 0.9 inches, the MDA is a bit of a brick, making for a tight fit in a jeans pocket; then again, it's actually slightly smaller and lighter (5.6 ounces) than the Palm Treo 700w. The phone fit comfortably in our hand and against our cheek during calls--or at least, no more awkwardly than the Treo or the T-Mobile Sidekick II.
To access the T-Mobile MDA's QWERTY keypad, you slide the front face of the handset to the right, revealing the keypad beneath. The actual sliding motion is a bit stiff, but the face locks into place with a satisfying snap, and the display automatically switches from portrait to landscape mode, though sometimes a little slowly, depending on which programs are running. The good-size buttons have plenty of room to breathe, compared with the cramped keys on the Treo 700w and the. Unfortunately, the MDA's keys are annoyingly smooth and slippery, and the uneven blue backlighting makes the keys tough to see in dark conditions, especially considering that the backlighting stays on for only a few seconds after you hit a key--a setting you can't change in the setup menu. The lack of a row of dedicated number keys on the keypad irked us; instead, numbers share the top row of letter keys, which means you must hit the Function button before typing a numeral. Alternatively, you can use the onscreen dial pad.
Back on the plus side, the T-Mobile MDA's 65,000-color, 240x320-pixel display is razor sharp, with excellent detail and rich colors, although we had a tough time seeing the TFT screen in direct sunlight. The main controls include a long, thin rocker for the two soft keys, a four-way navigational mouse, flanking Talk and End buttons, and another thin, horizontal rocker above the display that gives you one-touch access to your in-box and Internet Explorer. Along the left spine of the MDA is a small volume slider and a shortcut button for the handset's communication control panel--including Wi-Fi, Bluetooth, and synchronization options--while on the right edge, you'll find dedicated camera and voice-calling buttons, plus the phone's infrared port. A Mini SD expansion slot (unfortunately, the MDA doesn't ship with an actual Mini SD card) and the power button sit on top of the phone; along the bottom are the 2.5mm headset and power/USB ports, a latch for the back cover, and the retractable stylus. Overall, the MDA has a nice setup, although we wouldn't have minded a dedicated speakerphone button.
The back of the T-Mobile MDA has the look and the feel of a camera, with a ridged surface and a sleek oval surrounding the lens, the LED flash, and a small self-portrait mirror. When you're holding the phone sideways for snapshots, the dedicated camera button sits next to your right pointer finger. In a nice touch, a thin black sliver to the right of the camera lens acts as a rubber foot to keep the MDA from sliding off smooth tabletops.Like the Palm Treo 700w, the T-Mobile MDA runs on Microsoft's Windows Mobile 5 operating system, which is a blessing and a curse. The good news, of course, is that Windows Mobile 5 Pocket PC Edition comes bundled with Microsoft's Mobile Office suite, including the new and improved mobile versions of Outlook, Word, Excel, and PowerPoint, as well as the revamped mobile Internet Explorer and Windows Media Player. Messaging options abound: You can collect and send mail from POP and IMAP4 accounts, access your Hotmail via Pocket MSN, and send text and multimedia messages. Even better, the MDA will be upgradable to Microsoft's Messaging and Security Feature Pack for true push e-mail and real-time contact, appointment, and mail syncing with Exchange servers. The bad news is that unlike the Palm OS, Windows Mobile requires an inordinate amount of clicking and tapping. Important features are often buried under multiple layers of menus, and menu options are so small that you'll need a steady hand to click them with your stylus. Good luck navigating the MDA's menus while you're on the bus or walking down a sidewalk.
The T-Mobile MDA's wireless options are tough to beat. In addition to the IrDA port for beaming contacts, you get Bluetooth (good for wireless headsets and syncing to your PC via ActiveSync) and--drumroll, please--built-in Wi-Fi (which comes with a helper application that logs you on to T-Mobile's network of wireless hot spots), including support for WEP and WPA encryption; unfortunately, the handset works with 802.11b (not g) networks only. The MDA also acts as a world phone, thanks to its quad-mode GSM abilities, and it taps into T-Mobile's EDGE network for theoretical data speeds up to about 135Kbps. That said, the phone can't compete with the 3G handsets from carriers such as Verizon, Sprint, and Cingular. T-Mobile isn't expected to launch its own 3G network until 2007--at the earliest.
