Just to add to what Alan's said, and with apologies if appropriate as its arguably only tangentially relevant to your question, but you may be interested to keep an eye on the "Raspberry Pi", a 25$ computer (yes, $25) that's due for release in Jan 2012. It will primarily use Python as programming language although others will be supported. (Not entirely suprising given that the OS is GNU/Linux.) For more see here: http://en.wikipedia.org/wiki/Raspberry_Pi http://articles.businessinsider.com/2011-12-28/tech/30564049_1_computer-broadcom-foundation http://www.raspberrypi.org/faqs It seems that for anyone who wants to build his own device on the cheap from commodity hardware, something like this with a suitably configured Linux distro and custom Python code makes such a project a relative doddl. One can easily imagine building this size of device into a cash register sized shell, perhaps with a suitably sized touchscreen and drawer hardware interface, to build your own cash register. (Re touchscreen's I'm thinking of something from ELO perhaps, see: http://www.elotouch.com/Products/Touchscreens/default.asp -- I have a friend who is working on a kiosk using a normal ITX PC mobo and that uses an ELO screen with a GNU/Linux software stack behind it, so that's definitely possible...)
