Thanks, PB PM and Kickaha. Sounds like what I expected, though I may have been mistaken in thinking MS's revenue was dependent on corporate more than consumers, but you're probably right - I'm just seeing the focus rather than actual money.
As for the undercutting each others... I sometime really wonder.
I tend to hear more about how the companies buy up junk support contracts from those companies and pay through the nose for precious little and the executives act like they got a great deal while the IT people gnash their teeth over the contract. Or is this impression mistaken as well?
