If you want to have whole disk encryption on your netbook you will be dissapointed with Truecrypt because unless you burn a .iso on a CD first, Truecrypt will not allow you to encrypt your drive, but there is a way around this, it worked for me so it should do it for you too.
Download software that will mount your .iso CDs virtually , I used Alcohol120, this is not free, but the trial version worked well, the only problem I had was finding out how to mount the virtual CD with Alcohol120 as I didnt really want to waste half day reading the manual. Once you mount your virtual .iso CD created by Truecrypt you are ready to go, Truecrypt will allow you to encrypt your whole Netbook Windows operating system as normal.
You can also use Daemon Tools to emulate the mounting of your Truecrypt recovery disc virtually.
This is what the Truecrypt recovery disk looks like once mounted through a virtual drive using Alcohol:
You can also use this trick to avoid wasting a CD-Rom while installing Truecrypt on your desktop computer, it is pretty sad that Truecrypt developers are not allowing people to make their own choices and making the creation of an emergency recovery disc compulsory.
