Not to be pro-MS in this situation, but you have to think about where the other companies put their shit together.
The microchips inside your machines are probably built in some third-world nation where they treat people just as bad. Apple used to have a manufacturing plant (dunno if they still do) in Malaysia, with pretty rotten working conditions.
FYI, Dell assembles their kit in the States using prison labor.
Just wanted to bring up some points here before you accuse Microsoft of exploiting cheap third-world labor; because, to be honest, damn near every company in North America and Europe does it.
