I got this one used (after a month) on e-bay for about $174. It is basically new. It has a 14″ screen compared to the Samsung 3’s 11″ screen. It is running an Intel cpu and chip set. And it has a typical run time of 10+ hours before you have to charge it up.
So this Asus c300m is probably what I will stay with. Its funny though, Intel has gotten busy and designed cpus/motherboard chip sets with excellent low power usage. So for the moment Intel is handily beating the ARM folks at the low power usage game.
