Oh no, Dell isn't forgetting to do its duty to Microsoft. Just as promised, it has now bumped up the prices for folks wanting to stick with Windows XP Professional. As of now, the only way to get XP pre-installed is by selecting an option that also throws Vista in the box, and if you're specifically after Windows XP Home Edition or Windows XP MCE, you're thoroughly out of luck. On eligible machines, it looks as if getting XP Pro along with Vista Business will cost you $99 more than Vista Home alone, while having Vista Ultimate ride shotgun adds another $50. Or you can look at it like Dell's tossing in XP for free with those upper-level Vista packs -- whatever floats your boat. Let us know if you notice any different pricing arrangements.
