How well do you think the iPad Air will age? The move to a 64-bit processor causing a "20-30% increase in memory footprint" (according to AnandTech) and still having 1GB RAM is making me worried. The scenarios he used to test the memory were pretty light compared to what I put my iPad through. I web browse with multiple tabs and use twitter and switch through multiple games, so I have tabs/apps reloading on me frequently on my iPad 3, with some apps occasionally crashing outright. But I'll be pissed if I wait a year and the next one has 1GB too lol.
