All signs point to a March release of the iPad 3, with an enhanced Retina display and potentially a faster processor and LTE/4G data speeds. Any one of those would probably be enough for me to upgrade from my iPad 2, so in preparation I looked into selling my old iPad. When I upgraded to the iPad 2, I handed down the iPad 1 to my kids. I plan to repeat that pattern, and that frees up the original iPad. Even though it will be several generations old, my 16GB WiFi iPad 1 was worth over $200 at SellYourMac.com. I've written about them in the past, so I thought I'd put my money where my mouth is.
