Best tablets for sketching and everything else?

I'm a artist and I wanted to buy a tablet next week but , I'm not sure which one is the best for me. Ok I'm not talking about wacoms or anything like that. I've been looking at the Samsung galaxy tab and MOTO xoom also the HTC flyer for sketching capabilities. I'm not looking to create awesome drawings on it I just need a tablet to carry with me just in case I need to sketch something out really quick. Also I noticed the the iPad has autodesk sketch book but I don't buy Apple products because its non customize-able. would any other tablets have autodesk sketch book? And lastly the best tablet for music, apps, OS ect....with the sketching capabilities would be a plus! Thanx for commenting in advance :)
