Essential knowledge for all Mac users:
OS X Lion includes a new feature called Lion Recovery that
includes all of the tools you need to reinstall Lion, repair your
disk, and even restore from a Time Machine backup without the need
for optical discs.
This is how you can troubleshoot and reinstall Lion without a DVD or USB stick installer. Yes, in August, Apple is going to start selling Lion on USB sticks. But I think most of us really will be able to get by without them. That’s why the USB stick installers are going to cost $69, a $40 markup over the App Store download. Apple wants us to go download-only.
