Half of corporate PCs can’t run Vista?

If something is really shifting the market share in favour of Apple, than I think it is the fact, that Microsoft does have a real problem with innovating their OS on an outdated base of hardware. According to InformationWeek Gartner estimates that half of the PCs in corporations won’t be able to even run Vista. If need to upgrade infrastructure that is actually running well on the current OS (and probably would do so for another two or three years), than this is really be a financial problem.
