Not intentionally adding to the negatives --but I fail to see the attraction of backlit displays on bicycles. Sunlight so totally overwhelms them that near total washout is the best case for viewability (and if they made a backlight that could compete favorably with sunlight, its battery would either weigh a huge amount or would die in a few hours). I use electronics, but my GPS is tiny, used for routing and trip computer functions, and has a transflective display that only gets clearer with brighter sunlight. Backlit in sunlight makes no sense to me.
The back lit bike computers are for riding in the dark. Very handy if you need to know the time, distance home, etc.
