I did a review on this the day after it came out here:

Bottom line, its got a great build quality, and its the only Treo I could see myself using as my primary phone.
Treo design isn't my cup of tea though (not a fan of Qwerty's that are "always out", like the blackberry... wastes device real estate in my opinion), but I could see this as a clear winner to people who prefer that design.
