Porting webOS to a touchscreen ARM netbook (or convertible tablet)

Motivation

webOS is designed for users to search data and create new data, by means of a keyboard built in to each phone. Typedown filter lists allow users to quickly find an item amid thousands. Netbooks marry the high-input-bandwidth of a keyboard to the high (for a mobile device) output bandwidth output of a display. Netbooks running a desktop OS have stalled, because mobile design is different than desktop design. Netbooks running webOS will combine the ease-of-use of webOS with high-bandwidth input, making it ideal for mobile search and mobile content creation. Netbooks are ideal for command-line use.

Goals

  • normal use of standard webOS apps on a netbook
  • packaging open-source webOS to make installing it as easy as it can be.

Hardware

First priority is to identify suitable hardware, with a multitouch screen. We need to find an initial target platform that is currently available.


What kind of graphics chips can be made to work?


Possible

Always Innovating Touch Book Netbook v2 The company is all about open hardware and varying OSs.


Asus EEE Pad Transformer

SG-TPC TPC0801 Can't find mfg page, which would make it a poor initial target.

Toshiba AC 100 Toshiba's site doesn't acknowledge this, so it may have been discontinued.

Not Possible

chromebooks (no touchscreen)

Areas of Concern

  • low-level touch screen driver
  • gstreamer; what codecs are already available?

Tools

  • OpenEmbedded and Debian build systems
Personal tools
Google AdSense
