the Pre is the best device i have ever owned... here is my sum-up

Pros

-Web Browser is awesome
-Much more sensitive capacitive screen w multitouch with higher bit ratio making the colors much much more vibrant
-Games are out of this world!!!
-Best camera i have EVER had in any phone (forget megapixels, this rivals digital cameras)
-Cards multitasking, second to none
-Much nicer interface overall, nicer and easier email client, sms, music, contacts, etc. cant ask for a better put together package

Cons

- Build quality (includes speaker, creaky body, dead/stuck pixels, screen blotches etc. make sure your Pre is solid and it still doesn't guarantee it will last)
-Apps arent there yet (there is A LOT of trash in the catalog, the games are whats really shining ATM)
-Copy/Paste is half assed, can only highlight whole lines or paragraphs only instead of specific words)
-UI speed is ok but more speed would ne nice

thats should cover the basics...
