Graffiti vs. HW recognition

Zen of Palm
  sweet spot
  Windows CE is bad
  Palm is good
  Give users exactly what they need, done well, no more no less

versions of the Palm OS: 
v1 - v4: 
  based on Motorola 68000 "dragonball"
  big-endian data format

Garnet:
  based on ARM processor
  includes compatibility layer for 68k apps ("PACE")
  emulates 68k processor, but most of apps are making calls into
    Palm OS APIs, which are native ARM code
  can compile apps with "PNO" (PACE Native objects); then your code
    runs as native ARM

Cobalt:
  big, complex
  not shipping

Application 4-char signatures
