I bit the bullet and bought 4 of these today. Not sure if I'm gonna crack them open or not. All the ones at my costco have the Windows 8 logo on them for whatever that means. I know these went for $150 on ebay a few days ago, but I was willing to spend 10 bucks more to get it from costco even if it's only a 90 day warranty now. Just less hassle if I decide not to keep any of 'em.
