| The Bottom Line | While bulky, the iPaq h6315 offers strong performance and plenty of high-end features for professionals looking for an all-in-one device. | The AT&T Tilt promises to be the carrier's most powerful smartphone for business users with its full range of wireless options, Windows Mobile 6, and innovative tilt screen. | With a sleek design, good performance, and a robust set of productivity and wireless options, the T-Mobile Dash is an all-in-one hit and earns its reputation as a Motorola Q killer. | With the addition of Windows Mobile 6, the T-Mobile Wing adds a powerful smart phone to the carrier's lineup; however, performance falls a bit short of the competition. | Despite some niggling design flaws and the lack of 3G support, the HP iPaq 510 Voice Messenger offers outstanding voice-command features as well as the enhanced productivity tools of Windows Mobile 6. |
