Palm OS



The Palm devices were PDAs produced from 1996 to 2007 by Palm Computing. Although it was a pioneer in this field, poor management and growing competition from smartphones ultimately brought the Palm line down. It was succeeded by webOS. Almost all Palm OS games have been ported to iOS and Android devices, and since most games for Palm are no longer sold they're ridiculously hard to find.

If you're a collector who seriously wants to play PDA games, your best bet is the Tapwave Zodiac, a handheld game console that ran Palm OS and had a few exclusive titles of its own.
