Yesterday I got ipad(1st gen 64GB) 3G from local bestbuy (no flamewar between ipad-1 and ipad-2 please) for $529 (pricematching with AT&T online price of $529). This is my first iPad and sole purpose of it is to help my younger one with special needs to learn. He is having issues with his fine & gross motor skills due to certain medical conditions and school is getting him iPad to work in classroom, they also recommended one for home. Now my question is do I need to sign-up for AT&T monthly plan because I'm not intending to use it in near future. Can I use my iPad just on wi-fi and never activate it on AT&T ? Also what would be good case for this iPad keeping in mind that it is going to be used by 7 year old kid so lighter case would be better but at the same time it needs to protect it well.
