he Sony Clie PEG-NZ90 was a flagship handheld PDA announced by Sony in January 2003. This model was feature-packed, further improving on the capabilities of the NX series models. Like its predecessors, this handheld had a vertical clamshell swivel-screen form factor, and was powered by a 200mhz Intel XScale CPU, running the Palm OS (version 5).
The main improvement to this model, were the addition of a Xenon camera flash, and a higher-resolution 2MP built-in CCD camera with both autofocus and a macro mode. This camera was state-of-the-art for the time; capable 2MP cameras with flash were not commonly seen in mobile devices until several years later, such as the Sony Ericsson K750 which was released in 2005.
The device was criticised for only featuring 16MB of storage, which was seen as poor value for the high retail price.
In Japan, the NZ90U model featured a contactless FeliCa card reader IC. This enabled users to check the balance on an Edy (prepaid-money) card, or a Japan Rail Pass (prepaid travel) card.
