I'm not saying palms only, nor am I saying that a standalone device is not needed.

But for the person who already has a cellphone or pda and already keeps all their info on it and just needs $10 worth of circuit and an applet to display/log the info, then why not keep an eye in that direction as well?

I do think that in the year 2008, it is ok to expect a nice user interface when using an advanced handheld device. And my comment was in response to a "nice to have" feature in a user interface.

By having seperate circuits for each vehicle type (fuel injected, diesel, carbed) that communicate in a standard fashion, it also helps keep costs down for the do it yourselfer. The freeduino display device version can plug into them too and just leave out the rs232 bit and use ttl.
