Chris thanks for your replies.
The thing I liked with Openmoko was that before buying their phone I knew
exactly what I was getting as there is a very detailed community driven wiki
explaining how to perform common tasks.
Most computer websites seem to make the mistake of giving lots of specs
without any interactive content (e.g. demonstration and sample video outputs
of a webcamera).
Video demonstrations can always be uploaded to YouTube in WebM format to
supplement your website. The demonstrations could save time answering emails
and forum posts as they could cover basic usages of the products offered.
Regarding digital audio players: there are quite a few cheap available
players that work with Rockbox such as Sansa clip and clip+ that could be
offered instead of ones with proprietary firmware.
Regarding printer cartridges: the printer price is usually not really
important as the user spends most of the money on cartridges.
