I've been looking lately at the possibility of buying a smart phone, such as the iPhone, the Blackberry Storm, or the HTC Touch HD (which, devastatingly, will not be coming to the US)
However, with what I want to do, I realized that it would probably be better to pick up a UMPC.


Can someone shed some light on them for me?

I was looking at the Sharp Willcom D4, but it is Japanese only; performance is also said to be marginal.

Thanks for the help.
