Blackberry used to be able to do something similar. Obviously without any of the smarts, but you could view all of the conversations that you'd had with a contact across multiple services all in one place. It was handy to have.
Happy by Derren Brown altered the way that I choose to approach a lot of things in life. It's essentially an intro to stoicism. Something I had never really read about before.
It was really an attitude change for me, and realising that I can only control what I can. I can't control people's reactions to that. It set me off on a bit more reading into stoicism.
Will have to see where I can fit this in to a project.
