About half of the average business PCs in North America are unable to meet the minimum requirements for Microsoft's Windows Vista operating system, while 94 percent do not meet the system requirements for Vista Premium.
Within these figures, 41 percent and 78 percent, respectively, require RAM upgrades to meet the minimum and premium system requirements of Vista, says a new study by Softchoice Corp., which is expected to be released later this week.

These are some rather amazing statistics and are further evidence that companies will switch to Vista in a slow deliberate manner. The need to upgrade PC's is just one more factor along with checking home-grown applications for compatibility, purchase cost, training cost etc. The eWeek article goes on to state:

"Most organizations planning to deploy Vista within the next two years will have a PC life cycle that is affected by these factors, which, taken together, present a significant operational and financial stumbling block if not planned for well ahead of time," he said.
Preliminary user surveys suggest that 27 percent of organizations are planning to wait one to two years before undertaking a Vista rollout, with some 33 percent planning to wait between six months and one year.

The thing I find most amazing is that Microsoft didn't communicate more closely with PC manufacturers and corporate users to ensure more Vista-ready PCs were in place. Given that they were about 4 years late in rolling-out Vista you would think that they would have done more to speed up its acceptance.
What are you plans for switching to Vista?
