Is it really impossible for MS to use old WinXP drivers in the new OS ? I see no reason, why everything should be changed. Most of the old PC can not be moved to Vista, because there is and never will be drivers for 7. We allready decided to jump over Visva to spare money. We have about 14000 users and computers. It will be enormously expensive to move all and everything to a all-new system. Count it: - all the laboratory equipement and software for some 2000 systems - new computers - more memory to old ones - teach the users - run there trying to find drivers - server settings It is much easier to teach users to move to Linux than to Visva or 7. The environment of Ubuntu is much more familiar for or WinXP customeers. Many of them have allready moved to OpenOffice, because it was more familiar than the new MSOffice versions with the new incompatible file formats. Linux moves on evolving, not revolving as MS. Windows XP has so far been the best of MS Operatig systems even with its problems. Visva has been the worst of all 7 might be good enough, if only the real version could use WinXP drivers for at least NIC and VGA. If the old drivers will not fit, then thats it and goodbye. Another possibility is to stay with WinXP. It might work, if only we get support for about 3 years. This is the time to change the old PCs to new ones in our environment (remember the lab systems). Btw. it seems that more and more of the lab system developeerss are nowadays using JAVA. This way the programs can be used both in MSWindows AND linux. Even those system developers are pissed off with the quantum leaps MS takes with the new OSses.
