I had an opportunity to get a Touch for $200. And upon first playing around with it, it was nice. But the lack of keyboard was the main deterant(sp) for me. My friend however decided to go for it. The first thing he had me setup on it was the iPhone theme. The theme where you have to install Wisbar/Wisdesktop. That crap was a PAIN to setup, and even after getting it setup, it still wasn't working right. It took me a good 2 hours to get it right.
I wouldn't mind "upgrading" to the Touch if it had a keyboard and EVERYTHING that the Mogul has.
