The truth is Vista isn't that bad as long as you buy enough memory for
it, and are surfing and email.
But do things like VMs, video libraries, copy 800GB over the network...
Vista is pig slow. My Linux/UNIX systems have no trouble coping data 5
to 25 times faster than Vista.
Same with disk to disk copy. Put in a TB disk and copy part of the
video library to it and I will litterally get a nights sleep. On UNIX,
takes about 100 minutes.
