@purism i looked at the 13 and 15. In general they look like solid machines. Watched the youtube unboxing and review, pretty good. The only problem really is that it only has an Intel graphics chipset.
For 3D Mechanical CAD work i typically do using Linux Mint and a windows VM, the GPU is going to be my bottleneck.
Really nice hardware for a netbook though. Of course, if the idea was to make a netbook running Gnome3 probably an ARM CPU would have been cheaper.
