Re: 128 GB flash ... nobody will be able to work for long with so little storage
I agree - my MBA has 128Gb - with my ITunes library on a Nas - there is plenty of space to run any application I need, all store my core documents AND a copy of Win 7 running over Parallels.
I have a 32gb thumbnail sized USB key sticking out the side as my "just in case" that's never been used for anything but adhoc data transfers.
