Blue,
On the Mac I update them monthly. On the Win box it is an automatic process that happens daily because I choose to do it that often. In either case, it is not a burden. If some of the PC only software I use professionally were available on the Mac, I would request one at work. It isn't and VPC, which I use at home, is dog-slow when running through a few hundred thousand observations with anywhere from 5 to 125 variables in the statistical analysis and reporting program I use. Hopefully some day it will be ported to the Mac--it used to be available for it, but support stopped at version 6.10 and it is up to 9.0 now--and the changes and enhancements are significant. It is available for various flavors of UNIX, including Sun, and is available for IBM OS 390, but not for OS X at this time.
