If I was Apple, I would be all over Windows [app] piracy. While Apple has done a fair job convincing people that you can do anything on a Mac that you can do on Windows (ahem. Whether this is a benefit or not depends on your point of view…), but that’s not the biggest roadblock to people “switching”. The barrier is the cost to repurchase software on the Mac platform, which wouldn’t be such an issue if so many people simply don’t pay for the software that they use on Windows. If you paid zero for your copy of Office 2003 or whatever (not me, I’m still on 2000), then paying several hundred dollars for the Mac version (of that, and every other major app you use) is a significant barrier. Ergo: if it was harder to pirate Windows software, more people would buy Macs.
