Not happy with the 2GB, 4GB, 8GB, 12GB, or 20GB of solid state memory that came with your Eee PC? It turns out that you can upgrade it — if you have a really steady hand, a lot of patience, and a soldering iron. Hoschi at Eee PC.de managed to upgrade his 4GB unit to 16GB.
Update: As Tom points out in the comments, Hoschi’s colleage actually performed the upgrade, and he says the necessary software is hard to come by. He got it through his job.
