This is just a thought. When my iMac comes in Monday, I will be checking it quickly to see if it freezes like the lot of you. If it does and if indeed 10.5.7 supposedly resolves this, then perhaps I could join the ADC. I dev apps in Windows under C++ and C# so I could justify the transition. My question would be, would I be able to download a version (BETA) of 10.5.7 that could be installed on my iMac? Secondly, would it be useful? Lastly, this all depends on whether 10.5.7 does not release on Tuesday as rumors speculate. Thoughts?
