Take a look at these two posts from a ZDNet debate:
A poster under the name “jerryleecooper” says,
Vista is far more powerful than windows XP, and runs twice as fast. It is also much harder to pirate, and this point more than anything else has the Linux crowd in a panic.
and, in a follow-up post,
Are you saying that this linux can run on a computer without windows underneath it, at all? As in, without a boot disk, without any drivers, and without any services? That sounds preposterous to me.
Is this serious, or satire? If it’s serious, it’s absurd. If it’s satire, it’s genius.
