On a tangent, I was never able to acquire XPS with Linux, the online store for various European countries always showed it as non available.
I still have it. It was a good machine.
Most things worked correctly out of the box but occasionally WIFI didn't wake from sleep properly and the battery life was always a bit rubbish compared to any MacBook Pro.
I think that Dell have had too many models forever. Simplifying their line up is a good idea.
