I realize I'm asking this question within the omni forum group - but I am brand new to GTD and am in the processing of m first mindsweep and want to start off with the best program. I'm on macbook pro. Not on iphone yet - will be when the offer verizon.
I've read about a lot of glitches in the other threads and was wondering if you could give me guidance. Does omnifocus sync up with iCal? Should I be looking at Entourage or eproductivity?
Thanks for any and all advice.
