We usually go to a city somewhere and just explore, soak up the culture etc, We usually try to go on an adventure, Like when we went to Iceland in the winter and hired a car to drive round, That was fun, I just like to have a lot to remember and talk about when I return. I try not to visit the same place twice, Though I did go to Moscow twice as the Mrs wanted to go the second time.
Just Ubuntu. I have tried plenty of others but Ubuntu just seems to tick most boxes for me.
EDIT: I am looking forward to the new Pop! when it comes out, I will surely give it a try, No idea if I will switch then though.
