Last weekend there was a electronics fair near my hometown - among other things, I bought for € 15 a HP Jornada 728, complete with cradle, a nice device with Windows CE 3.0, a 200mhz ARM processor, 64mb of RAM (the model 720 had half). He was in good condition, I gave it a clean, replaced the CR2302 battery and found that is fully functional, complete with a main battery still in good condition after 13 years (from 2002):

After some investigation, I decided to install a version of Linux that could improve and expand the use of this handheld / tablet, making it a small fully functional PC: I opted for the old project JLime Linux, which I proceeded to install in a new 2GB CF - unfortunately WinCE remains in ROM, and the only way to do this is to initialize Linux from WinCE with a special bootloader, Linexec, on the first DOS boot partition of CF - the result is very nice and functional, although I would have preferred to have ONLY Linux through a flashrom... with my old HP PCMCIA Wireless card, the WL110, I am connected to the external network via provisional open hotspot from my cell phone:
