u cant do much on 1.51, u can only watch movies, listen to music and tahts about it, ofcourse play games you bought. No homebrew though.
If i were you, chenge it for 1.5, find one i got 1.51 week ago and took it back then went to near EB store and they had 50 1.5's in stock so i picked on up from them.
or update to 2.0 and atleast get on the net and some other stuff...
