The Penguin speaketh wisely. I can't imagine that any right-thinking individual would prejudge P5X based on P5Win user's experiences. Consider: Bryce 2 for Windows was the buggiest, hardly useable, most craptacular piece of sh^h^h garbage to ever exist. Bryce 2 for Mac was arguably the best version of Bryce for ANY platform EVAR. I've been using P5X since I downloaded it Thursday morning, and so far... (very minor niggles aside) I've found it to be a compelling upgrade from P4. See the thread coffee linked to. Of course, ymmv. If I gave a crap about politics, I never would have switched to the clearly superior Internet Explorer 5 from Netscape 4.7 back in the day. I use Mozilla now. ;)
