Really? Glad in many ways I am still using 10.5 then. I've no problem with stability. As you mention it seems quite rock solid.

I had no idea that the memory requirement for 10.6 or 10.7 was so high (I've heard anecdotal comments from non-tech friends). But then I'd also heard the official Apple line that 10.6 was meant to be better at memory management and slightly faster than 10.5 because the binaries were no longer dual PPC and Intel -- just Intel.

So, in God's name, why are the later versions so resource hungry?
