I have a problem with, after being a loyal customer for about 3 years now, having to pay exactly the same price for the upgrade as a person who just bought their CW.Even MS has an upgrade system that gives existing users a substantial discount for buying the new version as it comes out. I love the machine, but this decision has left me with a sour taste in my mouth. I understand the time and expense of developing a new OS, but how about a break for long time users? It appears that every year or so another $200.00 will have to be spent to keep up with changes. A G code machine is looking better and better all the time. Just my 2 cents, make that $200.00, worth.
