i just got one of the new win 8 tablets that runs full windows 8 not that crappy windows rt. now for a desktop i really don't know how well it would actually be.... but on the tablet its not as bad as i thought it would be really.... probably took me 30mins-1hr to get use to it and set it up my way. i put the start button on there just cause i like having it... do you really need it though? no, its just a convinence to us cause we are so use to it....

both my main desktops still run windows 7 and will stay that way..... windows 8 really is made more for a touch screen then kb+m std setup

but if your willing to learn the new stuff i don't see it being that bad, i just dont want to put it on my desktops that have no touch screens
