Here's something you may not be aware of: If you plan on getting a front light for your bike, be aware that some lights generate an electromagnetic field which interferes with analog wireless bicycle computers. I bought a Planet Bike 2-watt Blaze with Superflash front headlight, and it completely screwed up the Bontrager Trip 5W wireless computer I had at the time. For instance, the computer would indicate I was going 22 mph when I was stopped, etc. I ended up buying a digital bicycle computer--a Bontrager Node1--which solved the problem.

By the way--if you think you may put your bike on a trainer during the winter months, I also recommend you (1) get a computer with cadence, and (2) get one which can accept signals from a rear-mounted sensor. I've been using a trainer for the past three months, and I've found cadence to be extremely useful in helping me monitor my workouts. I use it a little less on the road, but I still find it to be useful there, as well.
