I have tried it on Fedora 17 and on Fedora 19.

Fedora might maybe have some kind of problem with the concept of a "system tray", which seems to be a mac and/or windows concept.

However, it might be the case that more grandmas use windows or mac than use various types of Linux? (Is Android a type of Linux?) so maybe that is okay?

What I could access of it worked, but without any apparent way to make its "system tray icon" actually appear on my screen I was unable to properly use it because for some reason or lack of reason its main menu is in or popped up from the system tray icon. The main windows that appear for example when you first fire it up and it walks you through creating an account and so on has no way to get to the main menu.
