Recently sold my Touch Pro, which worked perfectly fine. Just didn't like the form factor, especially considering it was my first SmartPhone.
The Treo Pro is absolutely fantastic! Guess I'm echoing what others have said, and it's amazing really it's not a more popular phone. It really is one "class" device, great form factor and well built. Definitely my 1st choice for a Sero plan.
Recently put on spb Mobile Shell... I'm lovin this thing, just a great phone. Much better battery life then the TouchPro, much more easily fits in pocket, and while the screen is obviously smaller as is the keyboard, I can live with it no issues. I can still easily text or surf when needed, which for me isn't extensive, so it's perfect
enjoy,
