"Rehmi Post of MIT's Media Lab is working on an under-$50, low-power, Linux-based handheld computer for the developing world. Information on Project Pengachu from his site."
[ Description from LinuxWorld link -- information on Rehmi Post's site is in the form of a slideshow, three of which are quoted below - LT ed. ]

"Design Goals

  • Small, cheap
  • Long battery life
  • Peer to peer ad-hoc wireless TCP/IP networking
  • Open software, open hardware
  • Complete software development environment on board
  • Reusable design for embedded computing (to enable TTT!)"

"Hardware Detail

  • Open hardware and software (no big SW license fees!)
  • Simplified backplane bus using 1Mbps SPI for low cost
  • On-board power management for long battery life (50mW while decoding MP3s)
  • 128x64 pixel onboard LCD, possibly VGA or NTSC output in next version
  • Projected system cost in volume ($50), easy to integrate into a cheaper few-chip solution"

"Software Applications

  • Software Footprint: < 1MB!!!!
  • Web browser, full TCP/IP software suite, NFS, web server, etc.
  • Native or cross-compile -- either way a full software development environment: vi, emacs, C and Scheme
  • MP3 audio and IP telephony support in hardware
  • Browse or navigate with onboard buttons and wheel; write code with external keyboard/mouse"
