The reasonably good embedded 3D will give vast numbers of people a taste of modern gaming.
Only if those 'vast numbers of people' are willing to pay in excess of 100USD more for their computers.I don't think a significant portion of people buy laptops with Intel chipsets because they think it's as powerful as say a GeForce 6 or 7. They do it because it's half the price and 4-6 times the battery life.
My TabletPC, in spite of being 3 years old, still has a useful battery life of 2 hours (was 8 when I bought it). My less than a year old laptop lasts about 45 minutes.
