I've installed Ubuntu for my little sister's PC, it fits perfectly with most of the things she does except for word processing.
She must use MS office (and not LibreOffice as it is not 100% compatible with MS Office) for school projects. I've tried installing it with Wine and PlayOnLinux, but that causes problems with Hebrew, it just doesn't write correctly. Now I'm pursuing other alternatives.
I'm thinking of trying installing a VM on on her computer and using it for all the must have Windows applications. How's that solution? Are there any better alternatives?
