The iPad has intrigued users since it's unveiling a few years ago. Having a small lightweight keyboard less version of a laptop has many advantages over its bulky, heavy counter part. You won't get the full power of it's predecessor, but it's compact size will let you take it places you can't take other computers.
For web browsing, it takes getting a little use to, since some websites have features that require a light touch for hover/drop-down menus, but after you get the hang of it you will be able to do most things the bigger ones do.
It will not run Flash applications which some of the hi-end websites use (including some game sites), so there is a lot of things you won't be able to do.. This may include YouTube videos, so make sure before you take it home.
It also has GPS integrated with Google maps. Key in an address or business name and it will take you right there. It shows you where you are on the map. Have not tried everything GPS can do, but would be nice if it had a "Find Buddy" feature.
You can get Skype and use it as a phone, which is nice being able to talk to anyone around the world.
The only things I did not like about it so far was: I could not view 2 documents side by side like I can using Simpletext in OS 9, which lets you drag and drop text from one document to another.. The other thing I could not do is open file sharing with my laptop running OSX 10.4.11. It was said to be able to do file sharing with computers running OSX 10.5.8 or higher.
When they get an open source developer kit, I will be interested in seeing how it will help me do development/control processes for my robot project.
eCommerce on the fly is a perfect use for this little 4G tablet, since you can place on-line orders anywhere you can take a cell phone. When you are in a wi-fi hotspot, save your 4G data transfer allowance by switching over to wi-fi.
