Chris,
I don't believe I've ever taken the stance that I don't want more memory in
the NXT. I can't imagine that I'd ever take that position.
I'm not opposed to more memory, but I am trying to see, understand and share
what little I know about the economics on some of this.
I was hoping for an expansion port to allow for easy growth of the NXT. For a
while I thought maybe that was what the USB was for, but alas it cannot do that
and appears to be limited to downloading programs.
Then I started thinking about what kind of expansion port I'd like. PCMCIA is
pretty limiting. My PC only has one slot. PCI is too expensive and difficult
to work with, so I started thinking about simpler interfaces. I2C came to mind.
It is a simple two wire interface often used to interface to serial memory
chips, but also interface to lots of kinds of lab equipment. I wonder if the
digital sensor interface is I2C or some other two wire interace.
I guess that the digital sensor interface is our best hope for expansion.
