I started using Ubuntu back when the quip was that it's the Swahili word for "Can't install Debian." I used LXDE for a while while Unity was in its bumptious youth, but I like Unity now.
BUT if I know I won't have to use an IDE for a meeting, I'll take only an Android tablet. With the latest updates it is within spitting distance of being a complete office work machine. Offline editing of Drive documents would complete the picture.
