What is a “bootable Lion installer” and why would I want one? Macworld’s Dan Frakes explains:

Unlike previous versions of Mac OS X, Lion (OS X 10.7) doesn’t ship on a bootable disc—it’s available only as an installer app downloadable from the Mac App Store, and that installer doesn’t require a bootable installation disc. Indeed, this lack of physical media is perhaps the biggest complaint about Lion’s App Store-only distribution, as there are a good number of reasons you might want a bootable Lion installer, whether it be a DVD, a thumb drive, or an external hard drive.

For example, if you want to install Lion on multiple Macs, a bootable installer drive can be more convenient than downloading or copying the entire Lion installer to each computer. Also, if your Mac is experiencing problems, a bootable installer drive makes a handy emergency disk. (Lion features a new recovery mode (also called Lion Recovery), but not all installations of Lion get it—and if your Mac’s drive is itself having trouble, recovery mode may not even be available. Also, if you need to reinstall Lion, recovery mode requires you to download the entire 4GB Lion installer again.) Finally, a bootable installer drive makes it easier to install Lion over Leopard (assuming you have the license to do so).

That newer article delves into some nerd-specific steps, but today Macworld posted an article, Lion DiskMaker makes it easier to create a bootable Lion installer, that seems easier.
