I would probably choose the Xperia X10 or HTC HD2.
Just looked at the Xperia X10 and if it works well, it could definitely be a major competitor in this market.
EDIT: Seeing things like the Xperia X10 really makes me think if I will get another iPhone after my current contract ends. The UI really looks impressive and I have always liked Sony Ericsson.
When is the X10 out? I used an X1 for a while and really liked it - but windows mobile was a bit clunky.
The new X2 is out either now or very soon... when is the X10 due to be launched?
Let's pretend they stopped making the iPhone, and you had to give yours up. There is no possible way to own an iPhone anymore.
What phone would you turn to?
I could get and afford an iPhone, but I see zero reason to get one. I don't care for mobile high-tech toys and in my book, a phone is there for exactly one purpose: To make an outgoing phone call when necessary.
Blackberry Bold 9000, not very into the 9700.
Besides, my wife has nicer gadgets and widgets to play with.
