Remember all of those people* who pointed out Vista’s DRM would only added more bloat and complexity to an already bloated and overly complex operating system? I think they were right.
On a side note, our Windows Update Server here at work had an update for Vista’s Norwegian translation for me to approve even though I only subscribe to English updates. How hard is it to properly classify patches?
* If you don’t, here’s one. Google for more. 
I just did a couple of tests, naturally being skeptical of the “64k link using only 256mb of RAM” claim. I duplicated a Debian ISO (105mb) in all of the tests
Vista, 2GB of RAM, SATA/150 drive: ~5s (just over)
Debian (no gui), 2GB of RAM, SATA/150 drive: ~1s (just under)
Win2k Server, 512MB of RAM, SCSI Drive: ~25s
So it is quite a bit slower than Debian (which is definitely to be expected), but hardly what the commenter claimed. But then, you can’t expect the Register to bother to do research, can you?
I hate the DRM as much as the next guy, but it is primarily in place because they are required to have it to license the HD content. If they did not have the HD content, people would be whining about that.
