It Does Little and Not Very Well
wiredog writes "A Washington Post (frryyy) review of the Nokia 770 Internet Tablet, a handheld Linux device. The reviewer complains about the lack of keyboard, poor WiFi implementation, outdated software, non-standard memory card, and almost as many crashes as an unpatched Win98 install."
Miniaturization is a problem, but it seems mostly for people trying to make many-purpose devices like these ones. It's not as difficult to build a very usable, very tiny interface on something that only performs one or a few specialized functions, such as the iPod or a cell phone. Trying to make a productivity tool, however, requires some ingenious compromise of size and functionality. Make it too small with two few buttons, it's too hard and not worthwhile for people to pick it up and learn. Make it too big with too many and it ceases to be truly portable.
I've thought about this for awhile and for the life of me I can't seem to come up with a compelling way of making a small, multi-purpose interface with a dealable learning curve. For these devices to succeed they have to be amenable to absolute manipulation in the same way that standard, non-digital physical objects are, and that's a mighty challenge that I don't think anyone has been able to succeed at to date.
