i was thinking of upgrading vista because Microsoft is slowly working out the bugs. i was running the system check for it and it said it would work except it said that my video card might not support windows aero. what is aero? can i disable that function and still use vista? my video card seems to work well with games that it doesn't support. i just click the "run anyway" button. will i still be able to do that with vista? my computer has an intell mobile 128mb graphics card (NOT upgradeable as it is integrated onto the motherboard), 2GB of RAM, 120GB hard disk, 1.73Ghz processor.
