and Microsoft is just too lame to bother with, here is my analogy of the available desktops.
remember when you got your first bicycle you thought it was cool, but once you started riding it around the neighborhood you seen what all the other kids were riding and you immediately focused on what you really liked as far as style and colors? it was the same with with my first computer, i got a nerdy win98 powered OEM gateway, but within the first year i started dabbling in Linux and loved it, i would dual boot at first until i got the hang of it and by the time i bought my second PC 5 years later i built it myself with the parts i liked ordered from one of the the usual PC builder' s sites, slapped Slackware on it (without KDE) and enjoyed the heck out of it, (sort of like building a bare bones bobber motorcycle from scratch) a beautiful bike that is as much a work of art as it is a machine with no cruft & kludge to get in the way or act as unnecessary dead weight.
