This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
I've used it and it worked fine, felt a tad slow to me too.
Because I was going back and forth between Mac and one Windows app it felt kind of clumsy, especially because of the different keyboard layouts. Because of that I eventually gave up on that one app (too lazy to delve into changing the keyboard mapping). I did manage to keep all my files and data on the Mac side pretty easily using Windows Sharing in System Preferences.
