I had an engineer friend from work who kept putting off getting a PC because they were constantly getting more powerful and cheaper. He did that for years. He missed out on all the use he would have had from one, and when he finally did get one the learning curve was horrendous. 'Nuff said?
I started with EQ6, and now use EQ7 on Windows 7 and also on an older Windows XP computer. It has a much better user interface than EQ5, as well as a lot more features. And I will order EQ8 the minute it comes out. I'm sure they must be working on it!
