It's easy to migrate from xp to Lubuntu for normal office use. Trust me. For CNC, assuming you are talking about computer numerical control, I understand your doubts. Anyway many CNC controlled machine use a set of standard instructions. I worked with different lasercut from Mazak and other kind of CNC machines some years ago and the majority were based on G-Code language. <a href="http://en.m.wikipedia.org/wiki/G-code">http://en.m.wikipedia.org/wiki/G-code</a> And if you like there are CNC solution based on Ubuntu <a href="http://www.linuxcnc.org">http://www.linuxcnc.org</a> Have a look on it. If you are not talking about this kind of CNC... Well please explain a little bit more deeply your problem.

Take my old company as an example employing 15 - 20 people on one site, have used XP since it's inception and is now being told by MS that they need to upgrade their six or seven machines to make them Win7 compliant. If we can offer something that enables them to carry on without that expense in these difficult times I am sure that would be a persuasive argument! Note that to this end I am in the process of clearing out my old netbook (1200 cpu 1.5gb ram 40gb HDD) to put a clean Lubuntu install on it for a meeting with my old boss on Thursday to show him how good it is and and a very reasonable outlay of nothing for either hard or software, possibly (even hopefully) a few hundred pounds to me for the installation of Lubuntu on their machines but that is secondary to getting the message out there. I have no worries over the 'office' functions (email, spreadsheets, presentations etc). The bit that concerns me is the CNC bit along with the software to 'port the specs' to the CNC machine as their specs often come from third party places who will quite possibly still be using windoze. I have not had enough experience of Ubuntu CNC to say for certain that there will not be any errors in then putting those files onto a *ubuntu box, and as that *is* their business they cannot afford any hassle however small and the transition *must* be seamless, as any hassle will have a negative impact on their business and they will end up going out and getting Win7 just for compatibility with their customers. If anyone has any thoughts on this please let me know ! Although I no longer work for them I still have a good relationship with the owners, and do not wish that to change as I cost them time / money or worst of all a customer!
