Except for the limited space, I'm loving my new Air (Mid 2012, 1.8GHz, 128GB, 4GB RAM). I sold my Mid-2007 24" iMac for it. I've mentioned it several how this is just a temporary until Apple releases the next iMac but after a few days owning it, I wondering why go back to iMac especially since I'm planning to buy an External Monitor (24" Dell UltraSharp U2412M). Sure the next iMac will be much better but do I really need it? Again, except for Handbrake & FrostWire, I pretty much do what I do on my Samsung Galaxy S3. Having the Air is best of both worlds, just last night I took my Air to work ust so I didn't have to wait until I get home to download the latest episodes of Awkward & Suits. LOL I have LTE (4G) speeds and on my lunch break it took 20 minute to download both episodes, roughly 2GB. Did you go back, why or why not?
