Dave, It really has nothing to do with the size of the drive, or saving money by cutting down the drive size. This is merely for remote support, I would much rather have a script downloading 200Mb updated iso's with bug fixes from my server, than 600+Mb iso's. Plus These machines are designed For there specific task, boots into the custom gui and shuts down. Thats it... no surfing the web, taking notes on gedit, or browsing the Ubuntu software center for games.
Im actually interested in seeing if the Roboboard 110 < http://www.roboard.com/RB-110.htm>, would be suitable for Linuxcnc.
