i have been holding out on an ipad because i hate at&t's service in my area and i would like a 3g model. i really do like the pay for 3g as you need it because i am usually around wifi but would like the 3g when i travel. i dont know anyone with an ipad yet and was curious about 3g performance? also, has anyone heard rumors of a new ipad with webcam? i just saw on engadget that verizon has a 4g sim coming & will that work on an ipad?
