Pat,
I have run CE since about 2006 and wouldn't go on any boat without it. I started off using a RAM mount for a Dell Tablet PC on a CD-22, moved it over to a CD-25, moved that to a 38 foot CHB and now have it on a Nordic Tug 42. It is an order of magnitude easier to use than a conventional chart plotter, and shows more data on the larger screens than you can ever see on a chartplotter. I have some engine data, course, depth, SOG, and nearby vessels (from the AIS). With a right click I can get current tide data for my location.
Two things to consider that I do. One is look at using a cordless Logitech trackball. It eliminates moving the mouse in a confined space. On the 25 I put it just to the right of the helm on the flat spot. Using a piece of velcro, it stays in place and you can work with it in rough water. The second thing is a USB powered monitor. I recently got a 16 inch AOC monitor on Amazon for less than $150. There are smaller monitors available and a standalone monitor will fit at the helm better than a laptop. You can also use an IOS or Android tablet as a remote wireless monitor, great for the rear deck.
Finally, you can install it on up to 3 systems (great to have a spare).
