Instead of using Cygwin and potentially upsetting your Windows side of things why not use Wubi to install Ubuntu onto your PC and then you have a main OS [Windows] and a experimental OS [Ubuntu] for all N9 type of stuff...You might also end up switching to Ubuntu for most stuff except for MS Office

Uninstallation of Wubi is simple just uninstall within Windows Add/Remove Programs and all significant Ubuntu traces should be gone from your PC.


The only downside is you have to boot into it everytime you want to use it...
