I just ordered the base 13" Air, and have a couple of questions. 1. I've heard of two options, Bootcamp and Virtual Machine? Which one should I use? 2. Where do you guys generally get your W7 copy? Do I have to buy a new one, can it be an upgrade, etc, etc. 3. For anyone using W7 on their current or last gen Air, how's the performance? 4. Since the SSD is only 128 GB, storage is obviously going to be limited. How much of my drive will be needed for running W7? 5. Last but not least, what are some of the main reasons people run both OS's on their Macs? One of my reasons is to do some light gaming which might not be possible on lion, but I'd like to hear any other advantages/disadvantages. I'm switching from a Pc to Mac after 11 years, so I don't know much at all about Macs.
