I bought the 1st or 2nd gen (over 2 yrs ago now) It's a really good machine, but I found Dell pretty terrible to deal with. I want there to be an alternative for that reason, but the latest XPS 13 ubuntu machine still looks about the best bet for a linux development laptop. Anyone else got the latest one? Or can anyone suggest alternatives to the latest one?
