The ipad and ipad 2 are similar but the Ipad2 is a little better. They upgraded the software and gave it a camera both regular and front facing. Also since it has a front facing camera it can face time or video chat. Also the ipad 2 is a little lighter and slimmer

Mostly the resolution, speed of processor and the weight is what make the difference. It is not enough to need to upgrade, it is simply like comparing a 20" TV to a 23" TV, it is only a very small difference.
