Linux is easy. I had Ubuntu on an old PC I rescued from work. Just wiped the HDD and installed it from USB. It was very MAC OS like. Used Libre Office on it.
FInally ditched it when I and the kids wanted to use more mainstream apps like Photoshop and Word etc for school. It was very lightweight.
Last thing I installed it on was a very old laptop my wife used to use. It was sloth-like. Ubuntu was lightening quick in comparison.
Yup - I used to have my desktop as dual boot but always used Ubuntu
it is probably still on there
had to stop using it much because I needed software that was not available on Linux because I needed it for work
and a few games I was playing were the same
shame really
funny thing _ I originally put it on there to try out some software I needed for work and it only ran on Linux
then had to stop using it because of other work things
Personally I have worked on school computers for many years and always thought it would be better if school alwasy used Linux of some variety (Ubuntu??) for teaching and for the kids to use
Everything in the National Curriculum can be taught using Linux
NOTHING needs Windows and the bits that requite something specific can easily be modified to use an Open version
but I have never seen any school that does
which probably explains why school get a massive discount on licenses!
