Hi The Psion doesn't run Windows CE but I am planning on learning its own language, OPL. This is a very high powered form of basic. It has a built in RS232 port which could connect into most programmers (among other stuff like IrDA). This also means that getting code on is easy. When I learn the language, I hope to make an assembler. The general idea I have is to keep the main development on the PC, move the code to the psion and only use the psion for adaptations to the code and programming. For on site updates this would be ideal where complete new code is used or for tailoring options for customers onsite. For me it means I can develop code anywhere, at school, on the bus whatever and program a chip without moving files about too much.
