Since the tablet isn't expected out until the middle of July, where are these tablets coming from? Simple answer really. 6,000 attendees of Google I/O will be receiving the Google Nexus 7 and it will be no surprise to see quite a few put the tablet up on eBay. One unit being auctioned has had no bidders yet and carries a "Buy it Now" price of $400.00.One seller wants $1,500.00 for his device. Not a bad profit for a tablet that will be priced at $199.99 in a few weeks. Of course, a buyer does need to be found first. You might see more goodies from Google I/O 2012 hit eBay as developers also will receive a Nexus phone and the Nexus Q Social Strreamer.
