I have one htc tilt. I think the Tilt 2 is as good as the I-phone, if not better-its got a big and brilliant screen; in our(non-scientific) head to head test, the Tilt 2 accessed my stock trading site as fast as the I-phone; and the Tilt 2 has the added bonus of a slide out keyboard.
I tested the Tilt 2 for 10 days-the battery life is robust! It lasted for two days of 8 hours of regular and varied smart phone use-internet access to check stock prices every hour and on the hour, e-mail updates every 4 hours, and constant phone use. Thats 16 hours of use before having to recharge. And the Tilt 2 recharges quickly-a couple of hours max!
The one knock I have which is really not noticeable if youre efficient in formulating your searches-the Microsoft interface limits your tabs to 3 or 4.
Ive had about a half dozen cell phones in 3 years-including a couple of the early Sprint mini-computers but HTC Tilt 2 is by far the best!
