- What features would a top-quality PDA have? It would be helpful to have an idea of what was usual on earlier models, say 2-4 years ago, as opposed to what's on the market in 2006, but I can fudge that if necessary.
- How long would a new, fully-charged battery function if the user was making notes and turned it off when not in use? What would the maximum expectancy be? Is it measurable in hours? Days? Maybe a week or two if used judiciously?
- Do any of these devices include games as part of the usual software, or are they easily available? I'm thinking of things like tic-tac-toe or minesweeper, nothing fancy. And would that drain the battery faster than note-taking, even if it was a simple game?
- Is there such a thing as a solar battery charger for a device like this?
Thanks in advance--it might as well be rocket science, for all I know about it.
TO CLARIFY: The scenario I envision has my character (with his PDA) in a crisis situation where he will have no access to electric power/way to plug in a standard charger for several weeks. He's going to be journaling his experiences. If he inputs for 20-30 minutes per day and doesn't do much else with the PDA, what's a best-case scenario for how long the battery will last?
Thanks, everyone--you've been very helpful! I appreciate the useful input. I think the premise that my idea hinges on is plausible...now all I have to do is write it.
