What's wrong? I mean the summary leads you directly to the conclusion you need to be coming to here:

"The average GNU/Linux user is now getting better absolute performance from their computer as well as better value than the average Windows user."

Seriously, that's good enough for me. Don't even need to read the article now...

Modern Sikhs typically carry just a dagger now and what they carry is a symbolic religious item. They are about as sharp as a butter knife.

Also I am sure they still have to put them in their checked luggage on planes, but even if they don't these things are not weapons and have no cutting edge. Even box-cutters are more effective.

This article really assumes that the expense of managing Citrix server farms will be significantly less than the expense of managing the XP machines.

Not that I am saying it wont be but as someone with a decent amount of experience managing servers and even with Citrix servers I'm not sure you can just say that.

Even if it's true, old habits are hard to break.

This statement is retarded: "have identified a massive miscalculation that makes the LHC safety assurances more or less invalid". The only thing invalid here is that statement.

Nothing in the article suggests that they have made a 'massive miscalculation. The study appears specifically focused on the chance that any critical research findings or theory could be wrong, it doesn't actually show any work that has a miscalculation in it.

This is one of the worst summaries I have read on Slashdot to date (que: "You must not have been here very long" response ;P)
