IBM WorkPad

IBM WorkPad was a line of portable devices, produced by Palm Inc. and branded by IBM. This line contained personal digital assistants (PDAs) and one subnotebook model (WorkPad Z50).

Overview
This line was released in 1997 and discontinued in 2002. After discontinuation of its self-branded line, IBM still offers the main Palm line on its site.

This IBM-branded line of PDAs were rebranded PalmPilots, with only a few software improvements (easy sync for Lotus Notes, DB2 EveryPlace, and IBM Mobile Connect).

Reception
Early WorkPad PDAs were received positively, similar to parallel Palm models; but later this conservative business-oriented line lacked notability, and multimedia options of latest models were described as relatively poor.

Models
WorkPad Z50 - 1999, subnotebook/thin client, powered by Windows CE, equipped with an NEC MIPS processor and with an 8.2" screen.

PDAs
All WorkPad PDAs have a similar gray-scale screen (with better resolution and contrast for C series, but with same physical size and similar layout); only the c505 model has a color screen. The WorkPad 30X can be upgraded to a Japanese version, using the Open Extension slot.

Accessories
Most WorkPad PDAs can use the same peripherals as the PalmPilot; for example, the external keyboard available for some models, and most WorkPads can be attached to a cradle for charging or connection to a PC; the WorkPad can be attached to a Palm cradle, and vice versa.

Some WorkPads (and sibling Palm models) can be attached to some ThinkPad laptops, using an Ultrabay cradle; This would be the Palm V, m500, m505, and the WorkPad c500 and c505 models.
