We are beginning to hear credible details on Apple's strategy to create a major assault on Microsoft's Windows Vista. During February, Apple lost some market share to Vista, but I'm not really hearing of people getting rid of their Mac in favor of a Vista PC. This share change may be much more the result of people who didn't buy last quarter in anticipation of Vista and still had money left, after the Christmas bills were paid, to get a new computer.
I have had several people now tell me they were so frustrated with the Vista upgrade process they were seriously thinking of buying a Mac and I've suggested that they wait. Because the Vista experience will get better and because Apple's Leopard will have a stronger bite than Tiger, the current MacOS version and it is due soon. It is not yet clear what the Leopard upgrade experience will be, but I'll bet it will still be better to get it preloaded if you have a choice. More importantly, I'm still expecting a hardware refresh to go with the new OS.
