28 cm width essentially excludes the 11.6" to 13.x" category, which are typically at least ~29 cm wide.

So you're probably looking at a 10.6" netbook.

Well, I'd probably take an 8G 29cm thing over 4G 28cm, but that doesn't seem to matter much, since I can't find any of either. The small ones all seem to either be tablets with a lightweight attachable keyboard (ie. prone to tip backwards) or they have a locked BIOS and can only run chromeos.
