Over the years I moved from QuickSilver to Spotlight (avoiding Alfred because I saw no real added value in it), and am now at a point where Spotlight is slow as molasses, barely usable during the first half hour after system boot, and, in general, far less effective than it was in the very beginning.
Having a really fast launcher on Windows would be another point in its favor from a productivity standpoint, and I have been bemusedly watching how the Cortana search bar has followed mostly the same trajectory as Spotlight in terms of bloat and unresponsiveness. So it is something to actually look forward to.
My suggestion is to call it Searchlight, in honor of the little flashlight icon that popped up as a spinner back in Windows 95…
