As part of the Back to the Mac event, Steve Jobs wondered what would happen if a a MacBook and iPad hooked up and the answer is the new MacBook Air. It's full unibody, full keyboard, full trackpad. Instant on. Great battery life. Great standby time. There will be both 13.3 inch and 11.6 inch models.
Pricing starts at $999 for 11.6, 64GB, 1.4Ghz. All models are 2GB of memory (sniffle).
