I don't own an Apple product, never have, but... How do you know for sure that Apple is purposefully "denying" netbook users? It's quite possible that they're using some optimized code in OSX 10.6.2 that uses certain CPU features (which could include newer versions of SSE, VT, etc.) that would be common to all of the Intel CPU models that they officially sell, but which are not present in the Atom, which has a significantly thinner instruction set than Intel's other CPUs. Executing an unsupported CPU instruction would cause big problems (such as an instant reboot), and Apple has no need to optimize OSX to work on CPUs they don't sell. Why would they?
