I think.
We stopped at a Cingular store the other day because I wanted to try out a Treo 680 (and four other smartphones) because I've now read enough to know that ease of use is a big factor. (And I have less-than-dainty thumbs, which plays a role.) (Thinking about that last sentence I'm forced to ask: Can one have dainty thumbs? Or are thumbs by definition not dainty?)
Anyway, the only reason I'm not entirely ruling out the Treo 680 is because the store only had a dummy model, and I'm not sure the typing experience is the same on a dummy model. If it is, the 680 is 86ed.
Also tried the Samsung Blackjack (also a dummy model), the Nokia E62 and a Cingular 8525. Didn't like any of them.

The Blackberry 8700, however, is a bird of a different color. (Which works better than a horse of a different feather...)
If I was to get a smartphone/pda/geekthing, it'd be this one. Nice keyboard. Nice screen. Lower monthly cost than the others. But there is still a monthly cost and it's more than I can justify right now. When the business requires it, I'll take the plunge. But for now, Diane needs new Christmas gift ideas!
