the massive challenge for Open (Source/Schematics/Plan/Recipe) Hardware seems the grafik-card… which often runs on closed-source drivers.

This is true for the raspberry pi (it even needs binary-closed-source-blob to boot), for the EOMA68 project and the pyra.

holy cow this thing is expensive! the guy behind it seems to be most interested in playing emulated atari games? 😀 (the best) 😀

so this thing seems to be more of a Open Source based nintendo DS – missing the LAN – port it seems not to be very suitable for doing your own server?

http://p.rdw.se/pyra-preorder.html

„It was announced that the hardware schematics will be available (final license undecided), which make the Pyra a kind of Open source hardware.[5] For compliance with the Free Software Foundation’s „Respects Your Freedom“ certificate the closed source SGX GPU driver was identified as the only remaining software roadblock („would be good to have free drivers, but we can’t achieve this for the GPU“ but the device may or may not run without a 3D driver, possibly free 2D driver is available or either could be made).[6] The certification is not only about bundled software, using proprietary software, or recommending it, such as non-free [emulated] games, but also about naming, e.g. Linux vs. GNU/Linux. In November 2016 a pre-release version of the Pyra schematics was made available under a CC BY-NC-SA license.[7]

Software

The operating system will be based on the common open source Linux distribution Debian which allows the use of already available desktop open source applications from the Debian ARM repository, for instance Firefox, Thunderbird, LibreOffice, GIMP etc. The around 1,500 applications, created for the mostly open source OpenPandora software ecosystem,[8] are expected to be available for the Pyra in short time by source ports.“

1 on the display; 2 on the sides; 1 on left side of keyboard (not visible when closed); 1 on the rear above the camera (between the flash LEDs; visible only when camera open)

All are on the Hinge

Video of the Prototype (at around 5:40)

The GPD Win seems to be too large to reach the Center Keys see here: [2] Also the Keyboard is not Centered, and the Layout isn’t optimal[3]

The bottom row of the dvorak keyboard layout cannot fit on the keyboard due to double-wide space

GPD Win currently works with 3D acceleration with free software, but is missing drivers for the INT33FE battery charger; touchscreen and sound are not yet functional.

Important for privacy and security, as the modem is closed and untrustworthy. More information about these issues at Replicantʼs “Freedom and privacy/security issues” page and Andrew ‘bunnie’ Huangʼs and Edward Snowdenʼs “Against the Law: Countering Lawful Abuses of Digital Surveillance” pub.

First Prototype without any Power Saving, should be much better with some Power Saving even under high load

Like the N900, per IRC discussion.
