I booted off on my 2012 i7 MacBook Air with an HDD (5400 RPM) and it's not that bad, honestly. The Bad Booting time (Mountain Lion): 1 Minute, 35 Seconds (EEK!) Opening Final Cut Pro X: 40 Seconds Opening Safari: 12 Seconds The Good Geekbench 64 bit performance: 7657 (Surprisingly as fast as the one with SSD. Nice.) I was expecting 2000-5000. The Bottom Line So basically, everything else is nearly the same in performance except for the parts where it needs to access the disk (booting, copying, loading, importing, etc.) So, would you consider a MacBook Air with HDD, cheaper price and more storage?
