I have only had it for 3 days, but I love it! The 8320 was a huge upgrade for me from the 8100, but this blows that upgrade away by 10x-15x! The only things that strike me as "cons" are:
the charging port location and its no longer mini-usb?
the lock button on the top end (accidental locks when pushing it into the case)
lack of themes (OK, so that isn't really a con
)
"pros" are pretty much everythng else, but the highlights for me are:
Reception is better
WiFi has more range
Camera is tons better
Keyboard is better
Looks are better
Things are faster
OEM themes have several folders
The thing is just nice!
