I've been pondering about the idea of whether or not to buy an ipad. Ive come to the conclusion that im gonna do it. 16gb will be sufficient enough memory for me. The big question is do i go for the wifi or wifi + 3g. Is having 3g really worth an extra £100. any opinions and personal experience will be much appreciated. secondly where is the best cheapest place to buy from and are they currently readily available?
