I was finally able to pick up my iPad today. I ended up getting the 16gb 3G version. I figured that 1 or 2 times a year when I would want or need 3G was worth the extra cost. Like you said if I sell it I should be able to recoupe the difference.
So far I am loving it. Then again haven't even used it for 2 hours yet.
You won't be able to put it down!
