Two RGB leds instead of the 6 leds (+ space for 2 more) we have now, sounds like a very good plan! Of course you should be able to customize the colors and which "messages" are displayed. Something like a "portable ubi".
Also, stereo speakers are not strictly necessary for me - I doubt you can really get any noticeable separation anyway on such a small device, and as Franko said, you'll use headphones anyway when you want good sound. And perhaps it would even be nice to have the speakers on the sides, of course in a spot that doesn't get covered by your hands. That way you can have sound output with the lid closed.
