The Bottom Line

Check out this PDA-phone if the Sidekick seems too childish, but we're cool to its lackluster phone performance.

Pros & Cons

    • Wi-Fi.
    • Excellent keyboard.
    • Poor phone performance.

T-Mobile MDA Specs

Screen Size 2.8

A Sidekick for grownups, the T-Mobile MDA ($399 list, available February 20) handles e-mail and Web browsing over Wi-Fi or EDGE with aplomb. Unfortunately, its lackluster phone performance and the stiff competition from other keyboard smartphones will limit its success.

The MDA is a rounded handheld with a slide-out keyboard, much like the Sprint PPC-6700—but smaller, lighter, and with better-separated keys. Dedicated buttons let you hit e-mail, Internet Explorer, your contacts, the camera, and the networking manager with one touch.

E-mail and text-messaging are a breeze with the snappy keyboard, though you can't really use the device one-handed. Turn the phone on with the keyboard closed, and you're running Microsoft Windows Mobile 5.0 on a 320-by-240 touchscreen. Slide the keyboard out, and the screen automatically rotates in response.

In addition to the Windows Mobile 5.0 pocket Office applications, which let you read and edit the most common forms of e-mail attachments, the handheld comes equipped with Clearvue's PDF reader. Microsoft Pocket Outlook supports POP3/IMAP, Exchange, and text-messaging accounts right now, and a free upgrade will add push e-mail from Exchange servers later this year. After adding a few programs, we had 20MB of free storage memory and 23MB of free program memory—plenty for everyday use.

Web surfing, either over Wi-Fi or T-Mobile's nationwide EDGE network, works well with Microsoft Pocket Internet Explorer. If you don't like IE, Opera now has an alternative browser for Windows Mobile 5 Pocket PCs.

Configuring Wi-Fi is a little frustrating, requiring clicking some nonobvious menus and dialog boxes, so we were glad that T-Mobile has a special application to help you easily log into its 7,365 U.S. hot spots. The built-in app hooked us up in two clicks. If you can deal with the configuration screens, you can also connect to any other hot spot.

When you're not in Wi-Fi range, the MDA works with T-Mobile's EDGE network. Using our MDA with a USB cable as an EDGE modem for a laptop, we got excellent Class 10 EDGE speeds of 140 to 189 Kbps. (You can also hook the MDA up as a modem over Bluetooth.)

Alas, the MDA isn't as good a phone as it is an e-mail device. It has quad-band support, so it can roam across the U.S. and the world, but we found reception only so-so. It was usually a bar or two behind the T-Mobile's SDA. In addition, the earpiece was so quiet we had trouble making out the other end of a conversation in a noisy environment. The speakerphone was a touch better.

A Bluetooth or wired headset at least fixed the earpiece problem, and you'd probably use a headset anyway—devices like this aren't all that comfortable to hold up to your ear. We paired the MDA with Jabra, Plantronics, and Logitech Bluetooth headsets, and ActiveSynced via Bluetooth with a Dell laptop.

Battery life in PDA mode was middling, at almost 5 hours of video playback with the backlight turned way up. That dropped to under 3 hours with Wi-Fi turned on. Phone talk time was good if not excellent for a Pocket PC, at 9 hours 37 minutes.

The built-in 1.3-megapixel camera—with the typical weak flash—is better than the SDA's. Our test shots were bright and had good color, though they were blurry at the edges and slightly over-sharpened in the middle. The camera will be fine for snapshots, though. Videos, as usual, are 176-by-144 at 10 frames per second.

The 195-MHz processor doesn't have a problem with basic Web tasks or with music synced via Windows Media Player 10. It can even handle full-screen video synced via WMP 10, albeit at reduced rates of 10 to 15 frames per second. On SPB Benchmark test suite, the MDA did surprisingly well on graphics, but scored very poorly on CPU and file system tests; the one processor-heavy application we tried, Skype, failed miserably.

Like so many other PDA/phones, the T-Mobile MDA doesn't look good when compared with the easy-to-use Palm Treo 650 and the powerful Sprint PPC-6700. The Treo is a better phone that gives an unmatched one-handed experience, though it lacks Wi-Fi. The PPC-6700, meanwhile, blends Wi-Fi with high-speed, wide-area EV-DO for an unparalleled one-two punch of Internet power. The MDA isn't a bad PDA/phone, it just isn't the best.

Compare the phones mentioned above side by side.

My Experience

I'm that 5G guy. I've actually been here for every "G." I reviewed well over a thousand products during 18 years working full-time at PCMag.com, including every generation of the iPhone and the Samsung Galaxy S. I also wrote a weekly newsletter, Fully Mobilized, where I obsessed about phones and networks.

My Areas of Expertise

  • US and Canadian mobile networks
  • Mobile phones released in the US
  • iPads, Android tablets, and ebook readers
  • Mobile hotspots
  • Big data features such as Fastest Mobile Networks and Best Work-From-Home Cities

The Technology I Use

Being cross-platform is critical for someone in my position. In the US, the mobile world is split pretty cleanly between iOS and Android. So I think it's really important to have Apple, Android and Windows devices all in my daily orbit.

I use a Lenovo ThinkPad Carbon X1 for work and a 2021 Apple MacBook Pro for personal use. My current phone is a Samsung Galaxy S21 Ultra, although I'm probably going to move to an Android foldable. Most of my writing is either in Microsoft OneNote or a free notepad app called Notepad++. Number crunching, which I do often for those big data stories, is via Microsoft Excel, DataGrip for MySQL, and Tableau.

In terms of apps and cloud services, I use both Google Drive and Microsoft OneDrive heavily, although I also have iCloud because of the three Macs and three iPads in our house. I subscribe to way too many streaming services. 

My primary tablet is a 12.9-inch, 2020-model Apple iPad Pro. When I want to read a book, I've got a 2018-model flat-front Amazon Kindle Paperwhite. My home smart speakers run Google Home, and I watch a TCL Roku TV. And Verizon Fios keeps me connected at home.

My first computer was an Atari 800 and my first cell phone was a Qualcomm Thin Phone. I still have very fond feelings about both of them.
