    I just recently did a clean install of lion on my MBA and iMac. Some of the new ML features intrigue me. Not sure I want to install all my apps again. Is a clean install necessary for the best performance? How would it be done? Same as a clean Lion install or do I have to save the ML program somewhere first? Thanks.

    It's not neccesary, especially if you did a clean install for Lion, although it's recommended if you're having problems with your current installation.

    I did an in-place up with no issues yet except that Parallels 6 doesn't work...other than that so far so good!

    I upgraded from the DP4, and I clean installed. DP4 was pretty buggy.

    A departure form my usual routine of clean installation, I have just finished installs on all 3 of my Macs. All running perfectly, and boy did it save me a lot of work.

    i did a clean install, I just prefer it. On my MBA after I did the upgrade, it also upgraded my recovery partition. So I just did a clean install from that.
