1. Hard drive – Excessive load cycling?
Unfortunately, there is now some evidence which suggests that using Ubuntu may reduce hard drive life due to excessive load cycling. However since this is not a new problem for Ubuntu laptop users, an appropriate solution probably already exists.
There is now a forum thread discussing the load cycling problem. The original blog post with useful comments should also be read.
2. Touchpad
The NC10’s touchpad does not work well using Ubuntu. Although some progress has been made on resolving some of the reported problems with the touchpad, this is still an annoying problem.
The original blog post outlines some touchpad problems. There is a useful forum thread on the topic.
3. Hotkeys
A number of workarounds for adjusting brightness have been discussed at length on this blog.
Considerable progress has now been reported on this forum thread which discusses the root of the hotkey problem.
