The older Cateyes (Astrale 8, Enduro 8) are my preferred Cyclocomputers some of the features on the commuter are more "gee wiz" and "feel good" than useful. I have no use for "carbon offset" as for ETA I can estimate it in my head without having to punch a button. Third as others point out the backlight is often sketchy and just sucks a little more life out of the computer battery. Also, many of us use a helmet mounted light anyway that provides more direct light on the display. In short the Commuter model doesn't excite me; however, the Strada and other more conventional designs do.
