Lion may be updated soon and bring some unexpected "features"." you mean you shouldn't upgrade minor releases because it can cause your system to b0rk? So it's not safe to upgrade even minor revisions (e.g. 10.7.1 to 10.7.2) because of "unexpected features" which could make your system unstable? So once you install one version of OS X, you should not upgrade unless shown by the community to be okay?
Is it easier to install a VM of OS X rather than a full installation of OS X on my computer? Perhaps it is better to install Win7 on my T420 and use OS X in a virtualbox or vmware VM?
The reason I want 10.8 is because of the iCloud sync/integration. That is *really* nice!
Thanks for fielding my questions!
