Mala Vista

According to a story today from The Times of London, Microsoft's profits for the last quarter are down 28%. Why? Microsoft couldn't get its act together in to release their new O.S., Vista, when they had planned to. Thus, Microsoft had to offer coupons so that consumers purchasing new machines at the end of last year could upgrade to Vista upon its release. My question: why bother waiting for an upgrade when you could go out and buy a Mac?
