!!! Introduction

There are a lot of interesting gadgets with very good features (screen, wifi, bluetooth, camera or other) that are currently unused. This is rather sad as they used to be awesome.

The main issues with reusing these old gadgets are:
* usually they miss some key feature to be useful every day (e.g. it's not a phone, so you don't use your Palm Pilot or Zaurus as a PDA anymore)
* they use software that is outdated and different from other older gadgets as well as newer ones. That makes it hard to add new custom software and means that it's harder to reuse multiple older gadgets.

To reuse older gadgets we need to:
* identify use cases where the old gadget fits (i.e. it has the required IO capability and processing power)
* find existing software or write new software needed for the new use case, this might require replacing the older OS or using tools that work on that older OS while being general enough that the software/skills can be reused with other gadgets

!!! Software stacks
!! Original stacks
There are a number of common software stacks that one can find on older gadgets:
* Linux with Qt, GTK, framebuffer or no graphics
* Palm OS
* J2ME on top of a proprietary OS
* Windows Mobile
!! Replacement stacks
When replacing the stack it is natural to mainly consider open stacks. This means mainly Linux and possibly some Java-like implementation.
The question is then to locate the relevant Linux version and hope that it works well enough:
* [Linux for Palm Tungsten E|http://palmtelinux.sourceforge.net/kernel.shtml]
* OpenWrt, DD-Wrt to handle WRT routers, WD Netcenter and a host of small NAS and routers.
