3. The 650M is faster than the 560M. The 660M is a good bit faster than that.
1. Nvidia is strong in mobile, but AMD already had switchable graphics. AMD Enduro is their new system; whether it's actually different from just plain old switchable graphics or not, we'll have to wait for reviews. Market share is going to tip in AMD's favor if Nvidia continues to short-change their customers in terms of GPUs.
2. Exactly my point, there is no competition. Lenovo could've done better. It's the real world, stuff happens. They'll probably release a Y480p, an AMD model in a few months - the Y460 and Y470 both had an AMD version / "p" model, so the chances are pretty high.
3. The 670M is only 20-25% faster than the 560M. The 660M can overclock to 670M levels (max OC v max OC is pretty close from what I've seen). It doesn't take a thorough analysis to realize Nvidia gimped their whole mobile line. The 680M might have some promise, but AMD's 7900M line should be uncontested on 28nm. Recall that AMD's 6990M AND 6970M are faster than the Nvidia 570M, that was when Nvidia put some effort into their line. 7970M blowing away every mobile GPU, only 20%ish behind a 7870 (meaning many will overclock to desktop 6970 performance.), 7950M being the 6970M replacement.. Nvidia's in for a reality check). At the very least, 670M and 675M will look like junk next to the 7900M's. According to Notebookcheck.net, the 7870M will be close to the 570M (maybe it'll tie a 660M at stock). And going down the line.. the 7750M is supposed to be faster than the Kepler 640M.
Also, the 650M is roughly tied with the 560M in most games.
Basically, I'm not saying any given Kepler mobile card is junk. The lineup is a mess, it's clearly gimped, and Nvidia is going to have trouble competing, as the 7970M is getting released in about 2-3 weeks.
