Once I installed this on my iMac, I was able to get ride of my Wyse terminal. Not only do I have more desk space, but being able to use this on my Mac is a godsend. Rich is so responsive to any problems that he clearly stands out in a world where service is no longer a priority for most companies. I have seem other "terminal emulators", but Rich has clearly refined his product over the years to make it the best. My partner has an emulator on his Dell that provides a very small window with no color options. Having a large window with all kinds of customizations is a real plus when you have to use the product for hours on end.
