The day Nvidia, MSFT and Intel killed the Netbook
For the time being there is no Optimus support in Xorg. There isn't one in sight either. It will require nvidia releasing specs (which it has not) and probably rearchitecting some major portions of the xorg infra to allow multiple drivers to be loaded at the same time and graphic primitives dispatched to the correct driver as needed.
These are netbooks that is not making my purchasing budget any time soon. In fact with Windows 7 full edition mandatory inclusion these are not likely to make any purchasing budget any time soon. It will be around 400£. Neither cheap, nor small any more.
Time to buy some more hinges for my old faithful HP NC4000. It looks like it will outlast its 5 years expected lifetime by at least a few more years.
