Well, I decided against buying the Acer models since whilst stock is now available, I don't think their build quality is up to scratch. The Samsungs X60s mentioned still haven't turned up!

Now I am considering the following:
Philips X56 - reasonable spec and very good price for a 12" notebook.
Asus V1Jp - top spec 15.4" notebook but no stock anywhere!

The Philips is very tempting, but on the otherhand its apparently a rebadged Twinhead notebook, and support/drivers/BIOS updates etc. are non existant!

So, erm, back to square one I guess?
