Quick note on user interface issues. A really good user interface can make using (& remembering, or being able to figure out, how to use a computer) much more practical. The downside is that wrist units with such sometimes have much worse battery life than older 'programming a digital watch like' interface units. The LiquiVision Lynx got criticized about this. Whether a unit has user replaceable batteries, a rechargeable battery option, can be recharged without a battery swap, these things can be of interest.
