If are anxious like me fore the release of Mac OS X Lion, then the wait is getting shorter by the day as July approaches we will get a closer date for release.

The instructions are pretty easy:
To upgrade your Mac to OS X Lion, you don’t need to drive to a store, bring home a box, and install a bunch of discs. All you do is click the Mac App Store icon, buy Lion for $29.99, and your Mac does the rest. Just make sure you have what you need to get your hands on Lion the minute it’s available.

Great to hear that Apple has made upgrade your OS simpler and affordable. A great move on the part of Apple, I would expect hundreds of thousands of users to upgrade within the first few days.
