Welcome to the forum. I guess you read some large books The Surface isn't small by tablet standards if that is what you are expecting but it is small by laptop standards. If size is important than you may want to check out the RT. If you need power and legacy apps then Pro it is
Oh well. Size doesn't really matter to be honest... the legacy apps and power was the choose for me. However, i could try it in a store before buying and i was really impressed in how much power this little thing can carry. But thanks guys!
