That's only partially correct. Out of the box, I've had issues with Google software for Linux and Windows- Linux ends up being less of a problem because I can customize it to force the software to behave how I want, but Windows isn't as easy to do that. Can't say I've used any Google desktop applications on OSX. I suppose OSX support may be different, since according to my friends who have worked/work for Google, their software support for multi-monitor displays on OSX may be very well be flawless since Google employees are generally Apple fanboys.
