I too have a Cateye Enduro 8. I don't really need to know anything. But it is nice to know how many miles I'm going (trip meter) and the total miles on the bike. Heart rate & cadence, I don't need to know.
I paid extra for the 8 so I could have average speed. This is not needed, but interesting to know.
Some feel that for commuting, one doesn't need a computer at all. For commuting, luggage & fenders are much more important, but I assume you have those.
