A wise man over on another forum states "The right bike is the one you will ride!".
I think the same theory applies here. Decide what YOU want and go get it.
As many have stated already, ya don't NEED any computer to ride yer bike!
As far as the Smile-O-Meter is concerned, well I think that is a physically internal thingy powered by fun and calibrated with wisdom. We each have to nuture and grow our own.
