Have had a 64GB Wi-Fi + 3G since day one. I do a little gaming, but mostly use the iPad as a feed reader (Flipbook, etc). I also do heavy mobile dev at work with multiple apps released on the App Store. I'm pretty sure work will be getting in a 3rd gen sometime soon so we can make sure our apps work well, but I can't say I'm not tempted to upgrade myself. I imagine I'd drop the 3G/4G on the upgrade, since I still have not activated on this one. 64GB would be a must for music and movies... All this to say, is it worth it? Speed, resolution, camera? Or just try to get rid of the "must buy, must buy" feeling by playing with the one that we get in at work?
