Wow, DJ Adequate, so apple should stagnate and not see 4Ghz in the next 3 years and not offer state of the art laptops with power and power efficiency because of benchmarks that might appear on Ars? OSX is a very good, usable OS, and in my informed opinion, has much better threading for an end-user OS than linux, let alone windows. Intel is Apple's future, and IMHO, the future looks a lot brighter than trying to figure out how to cram a G5 into a portable.
I expect OSX will get more "tech" with time, anyway, not less.
Here is the link to the review: http://www.anandtech.com/mac/showdoc.aspx?i=2436
The point is it seems to point out some fundamental problems with the Mach kernal--one's the G5 help mask. Moving to Intel, without the mask, these problems will become more apparent, not less. If your SQL server runs worse under OSX than under Windows on the same hardware, which will you choose to run? It's not OSX that has the problems, it's the kernal it sits on.
People think getting chip parity with windows will close the perceived performance gap. I'm not sure it will. You also get a lot of "Windows Sucks" posts here and on Slashdot, but the average user is comfortable and happy with Windows.
Anyway, here's another Arstecnichnica that pretty much sums up how I feel. Even if it was only a pipe-dream, while Apple was on a separate architechture I could always hope for some Mac Only breakthrough. Something that would launch my favorite computer into the lead. Now we have parity, and that's all we'll ever have with hardware--parity. That's probably good enough, but it's sad to see the dream die.
