eWEEK has a revealing article about Vista's graphics requirements that suggests, based on currently available information, that PCs using integrated graphics will probably not be able to take advantage of the most advanced UI features in the next Windows. This is of particular concern to laptop and Table PC owners as integrated graphics are extremely prevalent in portable PCs.

"Whether or not a PC has so-called integrated graphics and or the means to upgrade to an add-in card will become the fault line that separates the graphical haves and have-nots, analysts say."

The feature that "capable", as opposed to "ready" systems will be unable to use if the Aero theme in Vista. Systems without the graphics muscle to handle Aero's requirements will default to a less demanding "classic" Windows theme. It's not clear exactly what that means - Luna I suppose.

The number of Tablet PCs, in particular, that offer dedicated video cards is extremely small. If you're considering the purchase of a new PC of any flavor and aspire to be ready for Vista, it would be a very good idea to pay close attention to the graphics capabilities in your new system.
