Notes

With most web browsers, you can hover your mouse pointer over each device image to get its model name. Click the manufacturer's logo to open a new window to their product webpages.

When different international versions of a device exist, the North American model name is used.

All existing PalmOS devices are not shown in an attempt to keep this chart legible. For example, XPRO and hagenuk are selling rebranded versions of GSPDA smartphones in the China and Germany marketplace (respectively); IBM sold rebranded versions of various Palm devices under the WorkPad brand from 1997-2002, plus there have been various special editions produced for specialized markets or marketing purposes (e.g. Franklin Covey, epocrates, Supra, Claudia Schiffer, etc.).

In several instances, a pair of very similar devices were released (e.g. Treo 180 (with keyboard) & 180g (with Graffiti) or Clie NR-70V (with camera) & NR-70 (without). This is represented on the "tree" by one image, but with multiples branch-lines.

Most of the device images are not to scale (particularly noticable for the Kyocera and Samsung smartphones, the AlphaSmart dana, and the Clie NR/NX/NZ).

PalmSource maintains pages showing current handhelds and smartphones by all licensees on their website. Basic specifications and links to the manufacturer's product pages can be found there.
