As you've no doubt noticed, the deadline for the Windows XP downgrade option keeps getting pushed back and back, and it looks like it's now also getting more and more expensive, as Dell has now tripled the cost of the option on its consumer laptops and desktops to $150. As TG Daily notes, this latest move follows a similar increase to $99 on Dell's more business-minded Vostro laptops and desktops which, for the time being at least, seem to be remaining as is. Of course, you can always put that $150 towards a Windows XP-equipped netbook instead, which seems to be fast becoming the primary home for the venerable OS.
