We have absolutely no way of confirming the information ourselves, but according to iTWire, we can expect to really pay out the nose for the most ultimate version of Windows ever conceived, Windows Vista Ultimate. Like, say, something to the tune of $450 US. Yeah, we know that's a lot, but we're assuming that's for the single-license full install retail MSRP; and when you consider the fact that the single-license full install retail MSRP of XP Pro is still $300 US, it's not too drastically unrealistic.
Don't get us wrong, we're not exactly endorsing snapping up operating systems that cost more than the machines they run on but, you know, it is Ultimate freaking Vista, dude. Oh, and apparently Office 2007 Ultimate will set you back $679 US, too. Don't get dizzy now, just get your company to pick 'em up for you and you'll be well on your way to the Ultimate Microsoft suite which might have otherwise been used to put a nice down payment on a private jet.
