This is still the most unique and awesome PIM on the market. You can put in all kinds of information and while there are calendar views for weeks / months etc. the big plus is that you run on a schedule and can start items and record your progress and followups. There are color coded projects Marvels priorities so you can see how much each item is 'worth' to you. I could go on but let it suffice to say - you have never used anything like this. I run the pro version on windows 8.1 with no issues.
