Hey all...
Mac-Head here on a MacBook Pro (only a few months old). I downloaded the thing, then found the hack to burn it to a bootable disk...
--Download Mac OS X Lion from the Mac App Store ($29.99)
--From the Mac OS X Finder, locate the Mac OS X Installation file that was downloaded, right-click, and “Show Package Contents”
--Find and open the “SharedSupport” folder and locate a disc image file called “InstallESD.dmg”
--Copy “InstallESD.dmg” to your Mac OS X Desktop, this is the Lion disk image and what you’re going to create the bootable DVD from
--Now launch Disk Utility (/Applications/Utilities/), pop in a blank DVD, select the “InstallESD.DMG” file, and click on “Burn”
Then I made sure the thing was backed-up via timemachine to an external drive (then unplugged it)... and went and let Lion install.
A week of playing with it, I discovered that the Airport/network connection kept dropping after sleep. It wasn't keeping the name/password and asked for the authentication thing when trying to re-connect. Sometimes working... sometimes not. I didn't realize how often I close the lid and sleep the thing until I started having trouble. I thought I could deal with it then slowly went nuts over the week.
The problems not just me... found it in a bunch of forums.
Restored the old system to save my network sanity. Booted off the new Lion DVD I made and did the timemachine restore. I'm going to hold off until they post an update or two.
