I finally got one a few weeks ago, and it is incredible how easy it makes email and staying in touch.
However, I am disappointed in the ability to use web sites. It is barely functional, I could do much more on my Sony-Ericsson T68i. Basically, all I can do is use AT&T's mMode stuff, I can't even get other WAP sites to work like google or united's site.
At some point when I have more time, I might try to figure out if there's somethign tech support can do, but in the meantime, it's 50/50.
