Thanks for replies. Actually I only designed standalone applications based on Microchip PICs i.e. without any communication over any network (except 2 PICs that communicate with each other over a 433Mhz link).
What I would like is to be able to build applications that can be connected for example to internet (e.g. a board that could drive the heating sytem, accesible via internet). That means I need ethernet or wireless for communication and serial ports for actions. What about Gumstix?
