The Walmart link says the Asus includes the docking station (under "Accessories Included" as well as in the item description), for $496. The cheapest iPad at Walmart is $519 + $149 for the ClamCase = $172 more or 34.68% higher price.
I have no idea which is the better tablet, though; one runs Android 3.2, the other runs (I think?) iOS 4, they both have the same storage capacity, they both have HD cameras (I hope?)... The price difference might be worth it, or it might not be. Would need to do some research to determine that.
As for my question about why not get a real laptop, that wasn't aimed at you Lazy, just one of those "why would a person" questions. The idea of a tablet that can function like a laptop (well, a netbook) is cool, but tablets aren't exactly known for their blazing-fast processing power. Hell, the idea of multitasking (multiple programs running at once) is still kind of new on tablets. I certainly see the appeal in a super-light, super-long-lasting type of portable computer, but there'll be a lot of things these can't do, even with a keyboard attached.
