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.
