Ever since getting DL on my iPod Touch I have the best version with me on the go.
Having said that, I have noticed lately it seems off in the timing, the button clicks don't happen exactly at the moment I tap on the screen. Anyone else finding that? I have reset my iPod Touch to make sure that wasn't the issue but it's still laggy.
Mine is a second generation iPod Touch, almost two years old now. Maybe iOS 4 runs sluggish and it really is noticable with DL.
