One part of me hopes so, but another warns against it, lest Apple become nothing more than a software company. No, I don't think they'll be porting it anytime soon. If Apple releases all their software, iApps and all, for Windows, then they'd be losing a HUGE incentive for people to switch. When I worked for them, I and my coworkers touted the iApps above all else -- most of the people that switched did so because of them.
