    since it seems lion will only be available as a #%@#% app store purchase it seems like i might have to skip this version, i'm not going to buy my OS as an upgrade app.

    However all dev builds of lion come as installation images. So if i can get my hands on a pretty final dev build or R.C. ... will I be able to do a clean install with it and upgrade it to final when it is released?

    that way i would at least have a near final lion clean install on my new SSD instead of a osx 10.6 > osx 10.6.8 > osx 10.7 install with the first two not supporting TRIM.

    How do you know that what the Mac App Store gives you is upgrade only? There's a good chance it will be very similar in format to the DPs.

    The Developer Preview is from the App Store too. If you're so concerned about it, install 10.6 on an external drive and install Lion on the internal disc from there.

    It is currently possible to burn a dvd of the Lion DP 4 installer to disk. There is no reason to believe that won't continue under the GM version. Just burn the disk once you've downloaded it.

    I did a clean install yesterday. Went perfectly.
