Yah, I don't think a lot of previous desktop users will be too keen on the Start Screen.

I have been using a launcher for a long time (Launchy) and it's more intuitive for me to type "pro" if I want Poser Pro 2012 or whatnot.  Yes, the regular start has a search box that can do this but Launchy allows me to create my own keywords and I mapped the Launchy Box to my windows key.  (I mapped the right-click menu key to windows key in the event that I might ever use it).
