For those who think that using free software would be similar (naming ubuntu or even centos).

The real question is why a hospital is still running windows xp even though it's not supported by its own vendor.

The answer is vendor lock ins. The upgrade is not a matter of simple command. Upgrade cost involves more licenses and hardware upgrades (which is not needed as old hardware is fine, but this is how things work between microsoft and hw vendors) it's like you need a new buy watch to apply dst summer time.

Also mirosoft and old school desktop software vendors used to make sure switch or upgrade cost is really high ex by using non stanard formats.. to lock users from switching to mac or linux

If you remember active x and internet explorer specific vbscript...

If you use free software from an expensive but decent vendor like redhat you can upgrade software on same hardware

And if it software was expensive you can switch to centos, scientific linux or pay anyone to handle that for you are fair rate. There is no vendor lock in. Every thing is stardard and no vendor lock in.
