I had a computer and it was interesting, for a while. But after a while it was more of a nuisance having to keep the magnet thing on the spoke correctly oriented so I took it off. It never really told me anything useful; it was more of a geek gadget that was merely interesting. If you've got money to burn a Garmin 305 ( http://goo.gl/9R9GR ) might be more useful (although I use mine only for running).
For front lights I have two Planet Bike Blaze lights; one blinks and the other is on steady. Or, if it's dusk, they both are set to blink. On the front of my helmet I have the Flea ( http://goo.gl/Tivl7 ) set to blinking; I have the Bell helmet that has the mounting spot for it on the visor ( http://goo.gl/VfIAx ). For the rear light I have the PDW RadBot 1000 ( http://goo.gl/2tcBg ). The back of my helmet has a place to clip a light; I have a Planet Bike Superflash Turbo there, also set to blink.
I like blinking lights when I'm riding in the dark. Before my previous bike was stolen (I was stupidly using a cable lock) I had some Cateye blinking lights for the spokes. I need to get some more of those. I would like to get a MonkeyLectric but it's so big and bulky ( http://www.monkeylectric.com/m132s_gallery.htm , http://www.youtube.com/watch?v=DLtbeU8FJW0 ) and mega geeky.
