I have win 7 64 bit home premium edition installed on my pc but just recently had a chance to use a new pc with win 8 64 bit pro edition on it.
I hated it!
It was so awkward to find stuff and although I’m a visual person I just hated the tile interface. I have to say that I did love using XP pro when I had it installed; hated vista with a passion and love win 7.
It’s I suppose a matter of personal preference but I know when I go to buy a new pc next year that if it comes with win 8 already pre-installed I will be re-formatting and putting win 7 on it.
