Kindle books officially take over print sales at Amazon, pulp starts making retirement plans

The Kindle has been a huge success, no doubt about that, but we are continually amazed at just how big a success it has become. Amazon too, apparently. The company just issued a press release to announce that digital book sales have now exceeded sales of all print titles, both hardcover and paperback combined. As of April 1st, for every 100 print books that Amazon has sold (of any kind) the company moved 105 Kindle books, and no that doesn't include downloads of free titles. Also of note: the ad-supported reader that's shipping for $114 is now selling more quickly than the normal, $139 version. Proof, then, that people will put up with more ads in more places for 25 bucks.

Vienna University of Technology builds a 3D printer, 3D prints the key to our hearts

We've all spent a good portion of the past few years imagining what we'll do as soon as we get our hands on our very own 3D printer. Of course, if you're of the particularly crafty, Make Magazine-subscribing sort, you've probably already built a few of your own. For those who don't know a soldering iron from a freshly-burned hole in their hand, however, it's been a matter of waiting for the technology to come down in size and price. A machine designed by professors at the Vienna University of Technology still has a ways to go on the roughly €1,200 (about $1,700) price, but it weigh in at a bit over three pounds, and that's not for your run-of-the-mill extruder -- this breadbox-sized machine uses lasers to harden plastics, allegedly with enough precision to produce medical parts. Looks like picking out the perfect gift for your professor friends in Vienna just got a lot harder.
