Lifehacker reports that underestimated volume turned the Windows 7 Beta trial into another Mac advertisement.

You’d think that getting soundly beaten by Google and Yahoo over and over in the online space would mean that Microsoft would take the web a little more seriously. You’d be wrong.

Case in point: Today’s epic failure around the distribution of the Windows 7 public beta download. This morning Microsoft’s web servers fell to their knees under the pressure of constant web page refreshes by enthusiasts who want to volunteer their time to test Windows 7 after Steve Ballmer’s announcement the download would be available at noon today. (Since noon today, the download was there, then pulled, and back up again only if you know the direct links, and the promised product keys still aren’t available. There’s “no ETA” when they will be.)

Is it fantastic that Microsoft is offering this freebie preview? Yes. Is it shameful that they’d be so woefully unprepared for the demand it would draw? That also would be a YES.
