I currently have an iPad 2 which was the thinnest and lightest full size iPad prior to the iPad Air. I'm considering an upgrade to the iPad Air primarily due to the retina display and performance issues but I just want to know if the difference in weight is noticeable in day to use since I couldn't tell that much of a difference in the store. I'm also hesitant to upgrade because while my iPad 2 isn't the gaming monster it once was, it's still fast enough to keep up with iOS 7 at a decent pace, and the fact that Apple still sells the iPad 2 means that I'll be getting software upgrades for the foreseeable future. Because of this, and the fact that the next iPad will probably include the Touch ID fingerprint sensor, I'm hesitant about the upgrade. TLDR: Are the size, performance, camera, and screen gains over the iPad 2 large enough to justify an upgrade from an iPad 2 that doesn't scream, but still runs perfectly fine.
