Two Hands Good, One Hand Bad
The Palm Pilot was a breakthrough product that birthed a category, but Wireless Supersite Editor Ross Rubin says that new capabilities demand breaking with its traditions of a vertical orientation with handwriting input.The Danger Inc.-designed T-Mobile Sidekick has won praise for its gimmicky twist screen and integrated applications, but has been overlooked for breaking both with conventional PDA and phone design. Thats because while processors get faster, memory gets cheaper, and screens get bigger and brighter, input relies on that aspect of the human-computer interaction that evolves the slowest the human. The original Palm Pilot, with its vertical orientation and stylus-dependent input, was the first effective handheld companion. It inspired a string of knockoff market flops and eventually some officially licensed market successes courtesy of Handspring and Sony. When Microsoft stepped up to the plate with its first "Palm-sized PCs," it too mimicked the basic Palm form factor, but became intent on making as much of the device as accessible from one hand as possible through a mandatory jog dial and side buttons. However, these products and their Pocket PC progeny still rely primarily on the stylus for text entry.
Incredibly, that hardware design mandate has survived even as designers particularly Microsoft have touted multimedia and productivity applications that make the original Pilots look quant. One defense has arisen as handhelds have sprouted voice communication features. The rationale goes that if a phone can be used with one hand, so should voice-enabled PDAs.
