David covered it quite well. I have totally enjoyed mine. I hooked up to email ASAP, WiFi connections are a snap, and they nailed the book reader. If you have Kindle stock, sell it. Now that I have figured out how to download my Docs from the computer, I don't think I will be taking my laptop on business trips.
I can see this being a great customer presentation tool for anyone in the sign or graphics business. No, it is not a lap top, but it is everything you don't want to get your lap top out for. While watching TV, you can check email in a snap, go on the web, check the weather channel, or even reply to a forum like I am doing now. Or take it to a business meeting for notes, while being in touch. I watched Ironman on it the other night while the ol lady was watching some other TV program, and found it quite acceptable.
The lack of multi tasking is not that big of a deal. You can move from one app to another quite fast. They have already announced they will be upgrading the OS in June so it will multi task. I also think I will be getting the 3G one when it comes out. I have not had a problem findng a WiFi to hook up to, but I do travel to areas where it would be handy. You don't have to sign up for a plan, you can go from month to month. The 14.95 plan will provide you with all the data you need for a month. Remember, when you're at home, or at work, you will be on WiFi. Apple nailed it with the iPad...
