The Pyra is a wip open source handheld that is by far the most powerful and exciting especially if your a fan of emulation and homebrew, Evil Dragon has posted a couple of updates concerning the project, ill skip to the interesting bits:

CPU Board should be fixed now. Motherboard and Display board are done as well. Keymat is finished, just the DPad needs a tiny fix. Cases are finished except for the wiggling stylus and the too-hard-to-open battery cover.
Displays are finished, touchscreens are perfect. All electronic parts needed for the mass production are already lying around at Global Components. We've gotten a LOT closer to the finished Pyra now. The assembly of the prototype went pretty smooth (once you figured out how to best roll and assemble the LCD cable), so we're ready to start here.
