It seems that Apple is making inroads to replacing M$ Office on Powermacs, but given its need to recapture market share, would selling Keynote to Windows users be a way for Apple to accomplish this feat? I guess to do so would be to start challenging M$ on their home turf... in the same way that iPods have now begun to make inroads into the PC world. It seems that Apple is building up productivity tools. It also seems that most PC users do not have enough experience with Apple's excellence and are not willing to migrate and/or test the waters in OSX. Would the act of making Keynote cross-platform make Apple more accessible to those would-be switchers -- or at the very least, whet their appetites for something better than M$? At the very best, give Apple a new revenue channel? Perhaps Apple can sell it as a shareware type deal: try it for 30 days and if you don't want it, don't buy it. Otherwise, purchase it online through Apple. Please let me know what you think. Thanks!
