Internet Recovery

While the fact that Lion installs a recovery partition is fairly common knowledge at this point, a lack of physical media could leave users with a blank hard drive stranded without an OS. Thankfully, for some Mac users, there’s a solution

Apple:

If your Mac problem is a little less common — your hard drive has failed or you’ve installed a hard drive without OS X, for example — Internet Recovery takes over automatically. It downloads and starts Lion Recovery directly from Apple servers over a broadband Internet connection. And your Mac has access to the same Lion Recovery features online. Internet Recovery is built into every newly-released Mac starting with the Mac mini and MacBook Air.

I’d love to see this expand to other Macs as quickly as possible.
