I still use the Samsung Q30 (Dell had an uglier version of it in black only, I think it was the X100 - my Samsung is a beautiful candy apple red), it is a little slow but at just over 2 pounds it IS portable. It get that way through not having an integrated DVD/CD player and it has a smallish battery but the big battery is less than 1/2 pound. I saw the SS drive on Samsung’s site a while ago and was tempted but I think the lightest was the Samsung model that you are now testing - I can’t go back to 4 pounds.
Incidently, “it has ridiculously good design for a Dell” because it is a Samsung design just as the X100 was a Samsung design. Too bad Samsung is unable to sell in the US because of the Dell relationship, they make some super laptops - my Q30 was bought in London and has Korean keys.
