It is painful
I got a letter in the mail from Best Buy yesterday stating that I have silver status and therefore I can have 45 days to take things back with no fees. Oh, I am so tempted...
My husband thinks this would be wrong for me to do though
I hear your husband regarding the wrongness of "renting" an iPad from Best Buy. I rationalized it by deciding that I would give the WiFi version an honest evaluation to see if I really need the 3G. I also told the sales guy that I may decide to go with 3G and talked about their return policy.
So far I have spent almost all of my time in WiFi available zones but plan a trip next weekend where I won't be. I find myself using the online features all the time so the thought of not having access bothers me enough that I really do want the 3G.
Be smart, put that one on eBay while you wait. You may score quite a bit more money for your efforts.
If you don't you can always take it back and eat the restocking fee.
I thought about the eBay thing so I can hold onto it a few weeks longer but it will not be a "new in box" device so I would not expect to get all of my money back. Regarding the restocking fee - that is not the policy at Best Buy. If I had bought it at the Apple Store it would be a different story.
