I'm pretty sure Gordon didn't design or even spec the Bangle2. He just chose the best option already being manufactured (by SMAWatch on this case).
I, too, would like more buttons. However, in my opinion the power cost of a full colour display is not worth it. The Pebbles 64-colour display is ideal. Still very low power and sunlight readable, but enough colours to not need dithering to the extent the Bangle2 does (it's already too easy the make text unreadable).
