The first time I used Wunderlist, it lasted about one-hour.
I was already using an online task list embedded in my email, so having a browser tab dedicated to a check-list didn’t work for me.
I had signed-up for their email updates, and a number of weeks later, they sent me an email informing me that their desktop application was available. The idea of having the check-list on my desktop was appealing, and since Wunderlist looked so good, I decided I should give it another try.
Shallow, I know, but I’m glad I did!
