I keep thinking about all the discussions about external monitors and expansion and about the idea of having an internal / wireless solution to connect to "everything". I can't help but think that anything internal / powered from the portable is going to serve to drain the battery more quickly.
On the other hand, I was spending a few brain cycles trying to devise a way of putting an internal Bluetooth device in the unit without needing any hardware mods or consuming the M100 expansion bus. I was trying to think if there is a way to replace one of the 8K RAM chips with a special module that contains a Bluetooth module (along with a replacement 8K RAM chip), and then find some special signaling to communicate with it. Just my mind wandering... Ken
