With no USB drive on the new MBA, how can I reinstall Lion if I urgently need to reinstall it after a major system crash or something?
The new MBAs support internet restore.
what if you have a 2010 MBA and paid for the upgrade through the app store?
update: found instructions how to create a USB install drive.

Lion makes a recovery partition on your HDD so when you hold the option key on start up you will see all your partitions (In my case 3 because I have Lion then Bootcamp Win 7 and then the Lion recovery section)
