I have been considering purchasing EQ but right now with christmas around the corner I cant justify it. This morning while at a garage sale, I took a set amount of money with me, noticed an EQ4 sitting on a table so I asked about it and how much. She said it was 10 or negotiable. I said I only have 5 left of what I brought with me to spend and got it for $5. I was worried on the way home as it says for Windows 95/98 but worked ok in my laptop with Windows 7 in it. Now that I have played with it some I am thinking about the upgrade. Can anyone tell me any differences the upgrades have please?
