I have been using the BOLT development boards for a couple of years. I am sure they do not fit well with everybody's needs but I have found them useful. If you have read some of my other posts, you may notice that I am generally an assembly language programmer. I never write in C language.
I have a web page devoted to the BOLT board. It provides explanation of the features on the boards, some of the BOLT's weaknesses (as I see them), ways to expand and add on to the board, other modifications to the BOLT boards, and many other additional bits of information. The last update that I made to that page was just after the start of 2014. I have since learned more tricks about using it and should push myself to update my BOLT page some more.
My current project involves the use of a BOLT Lite board, a low cost graphic LCD display, an SD card, and a Stonyman (made by Centeye) digital imaging chip (basically a digital camera geared especially for small microcontroller use). All the parts of the project (including the BOLT board itself) are plugged into a breadboard.
Personally, so far, I have found the PIC18F2550 to be adequate for my needs. I am sure the grass can always be greener with a newer model.
I have had telephone and email contact with one of the primary individuals at Punto Flotante S.A. in Mexico and he was very helpful.
My page about the BOLT is located here:

NCR once refused to hire me because I was too short. I'm still waiting on my growth spurt.
