I've been using Mint for years and it serves my needs. It's kind of slow, they push advertising at you, but I got everything setup years ago and making slight changes to my budget categories takes no work at all. Syncing with my accounts is necessary because I definitely wouldn't put the time into software that requires any amount of manual importing. I login at least once a month to see how my wife and I are doing with keeping to our budgets, but that's about it.

Day to day, keep an eye on our shared credit card and checking account. We're lucky enough that we don't live paycheck to paycheck so I don't feel the need to track everything with a magnifying glass. That being said, Mint has been invaluable to set ourselves spending and savings goals and has made it easy to track progress on both. I'd be interested in a FOSS alternative so I could stop using an Intuit product, but haven't yet seen anything that is better for my needs.
