The Intel GMA 900 is a fairly old and low-end integrated graphics chipset. Intel has stated that it does not meet the requirements for Aero Glass, and thus have refused to released WDDM drivers for it. However, when pre-release versions of Vista allowed
XP drivers to run Aero Glass, the GMA 900 ran Aero perfectly fine.
My question is this: will the RTM version of Windows 7 allow the GMA 900 to run Aero Glass? This is an incredibly important question to me because it is the chipset my laptop uses, and it would be entirely pointless to run Windows 7 without Aero (someone might
argue otherwise, but a large number of new features are interface-based and require Aero Glass). Windows 7 is supposed to be optimized for netbooks but it would be completely pointless to put it on a netbook if half the major features are missing.
