Yes, that's it.
No matter what forum its is discussed on this will distill (eventually) to two opinions.
One, "not good, we may be shooting ourselves in the foot here", and...
Two, "we need to wait and see"..
If your in the second camp, good for you!
You are more of an optimist than I am.
But since I have the option of running my OS of choice on a larger array of hardware than OS4 users, I think I can be more discerning.
One, I can pay for an X5000, and spend more, but get decent hardware, or...
Two, I can wait for PCI-e G5 support when I will have have good hardware at a better price.
Thanks to my friends, I have this choice.
