I started off years ago with the Treo 650, which was an excellent PDA, great for email, ok for surfing the web, but not such a good phone. It fell behind the times in technology, though. When it wore out, I let a salesman talk me into an iPhone, which I hated. It made a terrible PDA and terrible for email. The only things it did well was surf the web and play music. It's horrible at everything else. Now that I've retired it, I've gone to a Blackberry. It's a good PDA and pretty good at email, but surfing the web on it is almost physically painful.

So all those functions are important to me: PDA, email, music, and web surfing. I want the Treo/Blackberry form factor with a physical QWERTY keyboard coupled with as large of a touchscreen as possible. Why can't I find such a device?

Thanks, but those are all horizontal sliders. I'd prefer the Treo/Blackberry formfactor that allows for one-hand use.
