As someone using the 2011 Macbook (bought about a month ago) I have to say some things really annoy me in OSX, some things less so. I'm slowly getting used to the Mac way of doing things, but still occasionally cmd-L to lock my screen only to find I have to go to a hot corner instead.

You can use Ctrl + Shift + Eject to lock your screen, also if you open up Keychain Access, then in options (Apple + ,) select "Show keychain status in menu bar", now you have a lock that shows up next to the rest of the menu bar icons, clicking on it provides an option named "Lock screen".

It's annoying that I have to do some sort of three finger claw salute. This is just me being lazy but is there any way to reconfigure the shortcut?

I don't know. I've never had an issue with running three fingers up one side of my keyboard!

Try Ctrl+Shift+Eject as a shortcut key to lock your screen without needing extra software.

Try Lock Me Now [1], which lets you lock your screen from the menu bar or configure a keyboard shortcut.

Why a separate app when Keychain Access already supports this out of the box?
