There is an article which i came across in a magazine called
custom pc the other day! it was a sneak peak into windows 8
which i dont think is released until jan 2013/2014 i think...
they have scrapped the editions of windows such as home,
pro,ultimate and instead of that they have developed a store
that you must pay cash for unlock different aspects of windows.
it was a very interesting piece of what the future looks like
for windows ( thats if the world doesn't end by then). I think i
prefer this so you get what you need and pay for it not stuff
that you dont.  I recommend this magazine!
