Ah, that does narrow it down significantly. I suppose frequently used programs vs. search depends on how wide of a variety of programs you typically use. So if you tend to use 9 programs regularly, and rarely anything else, frequently-used programs is probably more useful. If you use a wide variety and none dominate, search is probably more useful. On my laptop in particular, the number of programs I use regularly is low enough that nearly everything fits into frequently used programs, but that's less true on my desktop and my work laptop especially.
I do agree that the delay time for tab previews is too long, which is part of the reason I've rarely used them even with 7.
