It's a real problem! ;) :D
The Curve is way smaller than it looks on all those comparison shots. Really. I was impressed when I received my T-Mobile (Germany) device on Tuesday.
The 8800 (which I also love) feels like a Pizza-box compared to the Curve.
The touch and feel is very very good - the 8800 feels "edgier"...
My verdict: best BlackBerry so far (at least for my needs).
