All those other programs seem to be missing something once you have used Quicken 2007. I really like the clear cash flow reporting on the main screen as well as the streamlined online account updating (uh, especially when it works for all my accounts in one click). I currently run my XP Box side by side with my PowerMac G4. Quicken 2007 is really the only thing keeping the XP box on my desk.
If you go to the Quicken forums you'll see there are tons of frustrated users of Quicken for Mac. It appears that Intuit is maddeningly unresponsive to their pleas for a better product on the Mac.
