OK, so it's crunch time. I need a new laptop to do the odd simple cut-cut edit. However, I simply don't have the budget to splash out on a brand new Macbook.
So, keeping your answers as non-technical as possible (with as little 'you should know this basic stuff already' as well), will FCP7 run just as effiecently on one of the new Airs? Can I still use an external drive as the scratch disk, save myself a grand and yet still produce simple little edits on on the road?
