I am so very tempted by the Air. It is almost everything I've ever wanted the iPad to be. But I still think the iPad is rather impractical to tote around and pull out and use anywhere. I have the 4 and honestly haven't had it that long but I just can't justify the change to the 5 when the issue of portability still isn't really solved. Sure the Air is much quicker too in benchmarks - but in real life? I can see if you game how you would definitely want the Air over the 4, but I don't see a reason to upgrade from the 4. Plus... My mouth waters at the thought of the same screen and the same internals in a smaller package... Literally the perfect iPad, sans fingerprint sensor.
