As others have said the iPad Air will be smoother, snappier and physically lighter and smaller than your iPad 2. The Air will also have a longer expected lifespan. Having said that, the magnitude of the internal improvements will also depend on what you do with your iPad. If all you do is simple surfing, watching videos on a kickstand - then the improvements will be marginal. The iPad you have in hand is paid for, and you'll have to decide whether the improvements are worth the $500+. There are multiple videos on YouTube showing side-by-side comparison of various tasks on the iPad Air and iPad 2.
