RIM Building a Netbook?

Here is some interesting information pertaining to Research In Motion building a netbook? Wow, here are the details:

"It will be powered by an Intel Processor, 2 GB RAM and 120 GB hard drive. In essence, a basic machine suitable for daily mobile computing and more. Some other hardware specs include 10-inch LCD display, ethernet port, USB, SD medial slot and a DVDRW disk drive. It will be equipped with an internal 3G module that will supports a certain unnamed CDMA network for seamless connectivity as well as a SIM card slot."

It would amazing to see what RIM could cook-up for this. But what kind of OS would this netbook run on?
