The Blackjack has all I need, but it definitely doesn't provide the thrill I got with my last Treo.
1. To start, Windows is very hierarchical (you know, tree-decision based, from file to file to file....)
2. You can't type fast because the numbers will always be behind you, so you h a v e t o b e p a t i e n t. So you have to get used to typing slower, not convenient when you are calling room service on the way to your hotel so your dinner is ready by the time you check in!
3. Good visuals, size and reception. Battery charges quite fast and usually lasts 2-3 days (btw, I have the extended battery)
4. Although slow to boot up, it is quite reliable, I went through 3 Treos in 1 1/2 years, which is why I decided to try the Blackjacl
Overall I give it an 8 out of 10.
