I bought an SP2 - the latest was the 3rd machine. I had firmware and screen issues, and finally settled on something that lasted over 4 years. I still use it as a kitchen pc and the thing keeps on going - its a proper beast! Just got an SP17, am already on the 3rd through screen issues, but this thing seems like a keeper. It has no fan, can deal with anything I throw at it, and the battery is incomparable to previous versions. I get 8-10 hours!
