I know its really too early to know for sure but I wonder if the 160GB Drive from the iPod Classic 160 could possibly be crammed into the MacBook Air. I hope that apple didn't slim down too much and just left the 160GB out due to supply reasons. I'd be tempted to swap the drive with my 160GB iPod drive if I could make it fit and if the interface was the same on both. 80GB is just too little space.
