The evolution of the Palm (PDA)
Personal Digital Assistants (PDAs) run Palm OS and Windows Mobile platform. In recent years, have evolved from PDAs to smartphones that also run both Palm OS and Windows Mobile.
The first generation of personal digital assistants manufactured by Palm Computing in 1996 were named Pilots. Palm was a division of U.S. Robotics at the time. For two generations, these PDAs were called PalmPilots. Pilot Pen Corporation took the palm court trademark issues, so that since 1998, have been called Palm Connected Organizers or just Palms. However, PalmPilot is used to refer to all PDAs such as Kleenex means any kind of facial tissue for most people.
Jeff Hawkins, Donna Dubinsky and Ed Colligan, founders of Palm Computing, invented the pilot. They were working on handwriting recognition software, but as a researcher at the creation of software, they concluded that they should be working on better hardware. Hawkins carried around a piece of wood the size of the handheld device they were anticipating in his pocket for a week. Most people feel that Palm has benefited from third-party attempts to reach a handheld computing platform such as those made by Go Corporation and Apple Computer.
Pilot Pilot 1000 and 5000, the first, there was a serial communications port, however, had no infrared port, backlight, or flash memory. 1000 had 128 KB of RAM, 5000, 512 kB. They ran on a version of Palm OS. Finally, the original pilot could be expanded to 1 MB of internal RAM by means of a module update. The inventors felt that all Palm PDAs were to be hardware upgradable. What happened was that instead of upgrading the capacity, the memory slots external and firmware upgradeable flash memory were added after the Palm III series.
PalmPilot Personal and PalmPilot Professional, the next two Palmas, had a backlight, but has no infrared port or flash memory. Staff with 512 kB of RAM, the professional, 1024 kB. Palm OS has also been upgraded to version 2.
Because of legal disputes, Palm III and all those who have not followed the pilot word in their names. An infrared port, a backlight, and flash memory were added to the IIIS. Palm OS is updated so it could store programs or data in flash memory. Two AAA batteries powered the IIIs. It could also retain enough energy to a maximum of 15 minutes to keep data from being erased when batteries are replaced.
The founders left Palm and Handspring was founded in June 1998. Hawkins took with him a license to Palm OS for Handspring. The Handspring Visor was a clone of the Palm handheld computers, but includes a hardware expansion slot.
Palm IIIx had 4 megabytes of memory and an enhanced version of Palm OS (3.1). There are several variations of this Palm were produced. Palma VIII had connections some wireless Internet services in the U.S. Palm IIIc had a color screen. Palm V had internal rechargeable batteries, and this feature was included all Palms that came after it.
In 2000, Palm Computing spin on his own company called Palm Incorporated and later merged Handspring with him.
Palm handhelds continue to advance and today have the ability to become hard drives on computers using USB. Also merging with smartphones. The Treo 700w combines a Palm handheld with a mobile phone, email, SMS, and instant messaging.
