Hmmm the buttons are a problem depending on your cover aren't they.
There's T2 specific covers already showing on Amazon (like
this and
this), but since the size is so similar between the T1 and T2, you don't need to look for a 'new' one as such, just make sure it's one held in place at the corners rather than covering the buttons.
Perhaps look through the old
T1 covers thread for suggestions.
