User documentation

So, to sum it up, we can see that this device is going to be a REAL hit! SNAPDRAGON will make it feat along with 256MB of RAM. Not counting any posssible type of connecivity, implanted in te device. I really hope the sound quality will be on par with SONY Walkman dedicated players.
Even though it's not gonna be released until new 2010 year. Let's hope it will happn in January (my guess is late January).
