First of all, I'm not qualified enough for this... yet.
Then I don't have a working wifi module on my Pandora (I actually don't have a working Pandora at all these days, waiting for my spare LCD cables to come), and RMA is not an option due to various reasons.
So the one I've built first I needed to get a working Internet connection, and two people use it as well which means three devices less for ED to fix because of this right now, then the second one gives the opportunity to use dongles with big antennas, if I understood that correct, which also can be useful, and the third is just for practice and learning - I never could sit down and learn something, there always must be a practical, real-life problem to solve, even if it's simple. So far I've learned to set up the cross-compiling environment and tamper (simple) makefiles, this one is a little bit more compilcated.
