answer to the Macbook Air, the X300, has just been listed in Europe and the prices are, well, ridiculously high.
The lowest-priced version is powered by a Core 2 Duo SL7100 2x 1.20GHz LV, has 2GB of RAM and a 64GB SSD. It has no optical drive, which is not something you would expect from a notebook priced at €2848.90. It's listed here
If this isn't expensive enough for your tastes, you can opt for a 4GB version with a DVD burner and some additional goodies for €3244.20, here
