I just bought an iPad 2 and could use some help with case options given my specific uses when outside my house. I am a train commuter and will need a case/sleeve with some degree of protection because I will be putting the iPad in a bag or backpack every day and it may get jostled around some. I also expect to be using the iPad for storing and playing sheet music, so I will be putting it on a music stand or getting something like an iKlip (http://www.ikmultimedia.com/iklip/features/) to attach it to a mic stand. Any ideas of how best to deal with these situations would be appreciated. Would I be best off with something like a smart cover and some back protection case and then putting the whole thing in a sleeve while commuting?... then I could remove the smart cover when playing music (not sure if any kind of back case would be compatible with an "iKlip" like device).
