MacZOT is offering CrossOver Professional this weekend for $34.98 (50% off the regular price of $69.95).
“CrossOver allows you to install many popular Windows applications on your Mac or Linux computer. You can think of it as an emulator, but it’s different, because there’s no Windows OS license required. Your applications integrate seamlessly in OS X or Linux; just click and run. No rebooting, no switching to a virtual machine, and no Windows Operating System license required!”
