The holy grail!

After many months of searching I feel that I have finally found my ideal task manager - simple yet flexible, automatically moves undone tasks forward without haranguing you for not having done them, multi platform (i use a mac at home, pc at work and iphone and ipad on the road) - in addition, great integration with its sister product "Cal" which seamlessly talks to ical and google calendars - what more can i ask for - thank you
