HP confirmed 24 laptop models to be affected, and this number will probably rise. It's not just Apple products so don't jump ship just yet!
Check out the nVidia share prices for the last quarter, shareholders are obviously worried enough to see the price drop this much.
EDIT: The main reason i feel that there must be some truth to this is that nVidia are aware of the article as it is on there forum quite a bit, so if it wasn't true what harm would there be in coming out and saying everything is fine!
