Those talking of the NIT as a computer (a Linux one at that) is in the same class (or nearly) as Steve Jobs when he says the iPhone is Apple's netbook.

No the definition of a computer is not a problem at all. The definition of anything is based on what the general understanding of its function and form and context is to most of the people in the world.
A computer by that definitiopn means in generic terms - a PC like computer to most people. I get your point that a Voting machine is a computer and so is so many other things (like this for example), But just having a chip in a device doesn't make it a computer in general terms. Its the function that it serves that defines it more.

In that sense I don't think the iPhone is a Netbook or the NIT a Linux computer.
