So about three weeks ago I decided I couldn't live with my 15gb 3g's 45 minutes of playback any longer (it is the 3rd replacement from apple), especially for my Europe trip so I went out and sold my PSP to buy a 30gb 5g. Everything has been great except that when looking at friend's 5gs and Nanos, my Ipod UI/OS has seemed really sluggish and slow. Not just when I play a video or song, where I reasonably expect a short delay while the HDD spins, but just changing menus at normal speeds looks incredibly choppy. I wanted to see if anyone has had this problem and what they did to solve it. I'm still within the 90 day period and I bought applecare but have not registered it yet (I will soon, I just haven't gotten around to it) so I can take it back if need be, but I was wondering if there was anything I could do to speed things up...?
