Which Linux/Developer's PDA is the Best Buy?

benzdesignz asks: "I have been researching Linux PDAs and have enough to get pretty much any of them (Sharp Zaurus, iPaq, Yopy), but I am unsure of which one is the best. I am most likely going to get the Sharp unless otherwise advised. Links have not been included in this post since I am hoping to get answers from people already knowledgable about the Linux-PDA choices.". As an add-on to this question, Hellraisr would like a PDA for the developer: "I am in search of a PDA designed with the developer in mind. What I'm looking for (and I'm sure many others are as well) is a PDA that's probably running embedded linux, and allows simple compiles of not only Java, but maybe C/C++ and a few other languages. It would be great to have one of these in school where you could test out something real quick right in a lecture. Does anyone know of anything like this?"
