JetBlue wants to give you free Wi-Fi service during your flight starting next year. Well, it'll be free until the new service is installed on 30 JetBlue planes, which seems like a weird benchmark. Maybe that's why we're not running a major airline. Perhaps even more important than being free, JetBlue has set one very clear goal for the service, due to start in the first couple months of 2013: It must not suck. That would certainly set it apart from current in-flight Wi-Fi offerings, the bar for which is set so low that it is functionally a ditch.

Some scientists at University of Illinois have developed a pen that essentially draws circuit diagrams that will actually work, but no, you can't use it to draw a hamburger that you can actually eat because this is science, not magic, unfortunately. The pen uses a silver solution (the element, not the color) that allows the wielder to draw working electronic circuits on a number of different surfaces.

Printers have used metallic ink to print circuits for a while now, but this pen, while being cheaper and more versatile, also adds a little bit of unique, artistic flair to the process. This, combined with the fact that the ink will maintain connectivity even after being folded, could make some waves in the worlds of disposable electronics and electronic art. Sure, this thing probably isn't going to change the whole world, but the parts of it that it does change should be pretty awesome.

Not long after THQ announced its war on used game buyers, both Best Buy and Target announced they'll be starting their own used game trade-in programs. Both programs are similar in scope, but differ in details.

Yes, those are USB ports in that picture. No, it's not Photoshop. This exists. Or it will. Once approved for product safety. According to retailer FastMac, you could even install one yourself. Maybe.

"We will have an installation video available shortly so that you can see exactly what is involved and if this is something you feel comfortable doing on your own or if you will need assistance."
