hi friends. I am considering buying an ipad, confused between 2 and 3. I believe, the only upside ipad 3 has is the extra 512 mb RAM. Other things like quad-core graphics(which primarily gets used up in populating the extra pixels) and the new display are things i can live without. what my concern is that with only 512 mb ram, would the ipad 2 be in a good position to play heavy games like temple run, and other HD games that might come in the future? what has been the experience so far of ipad 2 users? Please guide me so that i can appropriately decide on this.
