You don't want much.
netbooks are to small to have CD's.
Ultraportabls notebooks often don't have CD drives.
You can install most things you can download off the net with no CD.
Windows does and Linux may support external CD's.
If you can rip a CD to an image you can use a program like virtual clone drive to mount the image and install it as if it were in a CD drive.
Hello, I'm looking at buying a netbook specifically the MSI Wind. I noticed that few or none of the netbok in this category have internal CD drives. So I was wondering if any sub-$500 newbooks have internal CD drives. And if there aren't any maybe post some tips on using an external drive or getting programs on without using CD's (i have an 8gig flash drive). And finally maybe some free/open source programs that me, a student could find useful that don't have to have CD's.
