Hi, i'm new here and i'm going to buy an Ipad 2. I never had one before so I have a few questions: 1. I'm very found of hd and youtube. Could you tell me if on Ipad 2 can I see youtube videos in 720p/1080p or just in standard resolution? 2. Could you reproduce 720p mkv files on Ipad 2? 3. In general, how look hd videos on Ipad 2? Thanks.
