I like my windows mobile phone. It runs all sorts of applications, and since it is a cell phone, internet anywhere, and all the goodies.
They made a new really slim windows mobile 2005 phone recently. Q2 maybe. It was some letter/number combination. Marketed as the slimmest smart phone on the market.
And of course touchscreen, wifi, bluetooth, irda, mmc card slot, vga screen, qwerty keyboard, all that jazz is what I have. But mine is a bit on the clunky side. They make them slimmer though.
