Just saw the 160gb version of the MSI wind at Micro Anvika for £293 plus it has the 6-cell battery which makes this just as good as the NC10, had a play around with one and noticed that with an updated bios you can now over clock the processor with the press of a button, so it goes from 1.6ghz to 2.0ghz and is covered by the warranty.

I've got an NC10 myself but this wasn't out when I got it otherwise I would've definately gone for this, much easier to run mac os on it also. Plus it has wireless-N which could be a decider for some people.
Possibly one of the best netbooks out there with the NC10
Comes in three colours, Black, White and PInk and they seem to have plenty in stock. Had a look at a few other prices online and the seem to be in the region of £305+ for this model.
