|The Palm m500 series of handheld personal digital assistants consisted of three devices: the Palm m500, Palm m505, and Palm m515. The series was a follow-up to the popular Palm V series with a similar, though slightly shorter, footprint and form factor.
Like the Palm V, the series had metal cases (although the m500 had a plastic back plate) and a 160x160 resolution screen. The distinguishing features common to all in the series are a SD/MMC expansion slot, faster processor, new faster USB sync interface, new software functionality, new vibrating alarms, new indicator light, and a mechanical fastener vs. hot-glue case construction. Later models introduced an improved version of the color display and more memory.|
