I don't have a tablet, but if you were looking to get one, you need to know which tablet is best for you.
iPad - with iOS, this is no super computer. Just a media machine with the same OS as the iPhone, just on a bigger screen.
Android Tablets - with Android, these tablets can do multitasking features. Media functionality is a little less than the iPad, but for its price, its a bargain (Samsung Galaxy Tab starts at $399).
Dell Tablets - They were DOA, but with the up and coming PALM OS aka WebOS being added, they will be a nice functional tablet to use for all needs. But, no one knows a release date yet.
Acer and ASUS will have their tablets with Android as well, but those tablets are in the works with Androids Gingerbread OS.
If you need one as a computer, for drawing and design, then these tablets will not fill that need. You're better off getting a Wacom Tablet do the job, and save yourself money. lol.
