Nuh nuh no.

That 'purchase' got you at least 3 versions of the software.

The dev install ISO for 4.5

The straight, normal install ISO for 4.5

Both of those make installation CD's like everyone else.

But you can also download what they call the Lindows CD (ISO), which also makes a CD, but this CD is Not for installation, but to run the Lindows OS from your CDRom drawer.

Fully contained, no installing to an HD.

That's why some dudes will take these and plop them on a 1 gig key drive. You can run whatever you need, off someones USB port.
