Having used the:
Treo 650,700WX,750P
Samsung Smartphone
HTC Mogul and HTC Touch
I came to the conclusion that even though I loved tinkering with many of these phones. None of them where extremely reliable or user friendly out of the box.
The HTC Touch was most definitly the best phone I have ever had, but everytime I had a nice clean rom, whether oem or custom, after a while it always came with problems.
Soft reset was always a must withi 3-4 days to keep things running. It was either a good phone or a good PDA, but never both. Lets face it. Windows Mobile isn't as stable as most high use consumers would like it to be.
I do think HTC rules the market with user friendly layouts especially on the new Diamond, but I couldn't wait.
-The Iphone is super user friendly and a lot of things just make sense. Dialing a number the feedback is actually realtime instead of a beep and a number showing up a moment later
-You can actually browse the web really well. Though Opera 9 came very very close, but again buggy.
-It's an Ipod, duhh
-Visual voicemail. Just like the Instinct.
- User interface has NO lag at all. It just works.
Things I don't like about the Iphone
- No video
- Not a great camera
- ATT is more expensive, but the coverage is much better (I'm a pilot and coverage was a big issue with Sprint)
- No external storage
- 3G is faster, but no EVDO rev. A
