I absolutely abhorred win7 when I upgraded but I was with xp for so many years and loved it to bits haha. After a while though I've really come to enjoy Win7, it's a lovely OS, still a little buggy but I have tamed it!
I wish so much that I could allow myself to spend thousands on a computer but I don't like to waste money on something that would soon be classed as obsolete D: >< . I just wait patiently for sales before I buy anything ; ; lol
