I've been a Cool Edit user since the days of CE96. Back when I first went that direction, I was using Protools at work but, despite my familiarity with PT, chose CE for my home set up. I preferred the User Interface and also like the fact the even the early version of CEP used 32 bit Floating Point as it's internal processing standard...it was getting on for 10 years before PT caught up to that one.
The one problem you may start to have is running software designed for the Windows 95/98 generation on more modern operating systems. Clearly it works for you but I've heard of others having problems.
