I checked out the Ipad at the Verizon store, but I ended up getting the Samsung Galaxy Tab. It includes a front and back facing camera, GPS, it can multi-task and is about half the size as an ipad. Another feature is that the galaxy turns into a wi-fi hotspot so I can use my laptop on the road using the cellular network.
I liked the portablility of the smaller device. I have had it for about a month and take it virtually everywhere with me. I barely even use the desktop for internet surfing anymore. As for using a laptop, most of the time you are on the road and need to do email or check something on the internet, you need to lug out and boot up a PC. With a tablet, it you can keep it on all of the time, like a cell phone and it "boots-up" at the touch of a button. I get about 7-hours of use-time on a charge and standby time is more than a day or two. I think the Ipad is about 10 hours of use time.
Neither device replaces a laptop, but they are complimentary
