Microsoft StartKey, Replacement for U3?

After a year of waiting, Microsoft has finally announced what they have been doing since they struck a deal with U3. The app that Microsoft is replacing U3 with is called StartKey. It appears to basically be U3 on steroids, essentially allowing you to store your files, mobile apps, and have their roaming profile all on their removable storage device. We say removable storage because Microsoft isn't just going to limit the app to USB drives, but SD cards and possibly more.

StartKey promises to turn any workstation or kiosk into your own personalized workspace. Microsoft is currently testing these drives out and sources say that the drives should be available in at least beta for before the end of the year. It almost all seems like a waste, as those of us that require a workstation set up the way we need it with our apps and files already carry around a laptop.
