The G1 vs. the iPhone

How the two 3G smartphones stack up against each other

Call quality Although no one has yet seen how well T-Mobile's cellular network will perform under the demands of the G1 phone, we can examine both T-Mobile's and AT&T's past reputations for call quality. Although AT&T has typically ranked ahead of T-Mobile in JD Power's annual wireless service surveys, the latest survey shows the two carriers are now even in terms of call quality and in service reliability. Smartphone users who look for call quality first and foremost, however, might consider passing over both the iPhone and the G1 for one of Verizon's smartphone offerings, since Verizon has for years come out on top of JD Power's call quality surveys.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
