While the DRM part is accurate (and why is it Microsoft's fault the company that provided the music originally pulled its license? Clue: it isn't its the fault of the folks that OWN the licenses to the music, not Microsoft, but its easier to throw rocks at Microsoft than it is some record company right?), the rest of the Facebook (now Slashdot is trolling Facebook to find AntiMicrosoft and DRM rhetoric?), is simply put, bunk, or this fellows crappy computer. I too use a Zune and have NONE of the issues he is having. While the Zune software can take a few seconds to start, mostly due to the login to the Zune Music Store, it does NOT lock up your computer at ALL. And plugging the Zune in works just fine. Closing the Zune software is instant and painless. Pesonally I think its PEBKAC, but again its easier just to blame Microsoft than it is the end user...
