It isn't just Win 8 though. Back in the day, Macintosh System 8 (maybe 7 had it in later versions I can't remember) had a thing called "Simple Finder". It had a bunch of tiles, very much like those in Win 8 and in iOS.
More like the 1991 GEOS Pro..
The above is my SKYTEX SKYTAB running Windows 8 32-bit..
