Sony CLIÉ UX Series
premium multimedia PDAs announced by Sony in July 2003
The Sony Clie UX series were premium multimedia PDAs announced by Sony in July 2003, running Palm OS (version 5). These devices were advertised as being a "personal entertainment communicator", a purpose not dissimilar to the Apple iPod Touch released in 2007. Two models were released, featuring a "palm-top" clamshell design, with a landscape tilting and swiveling LCD screen.
The UX40 and UX50 were largely identical, with the exception of their wireless connectivity. The UX50 included both bluetooth and built-in Wi-Fi support, while the UX40 was US$100 cheaper but only featured bluetooth. Users of these devices frequently experienced difficulty connecting to other devices via Bluetooth. The UX40 was, for a time, sold at Costco, while the UX50 was not. A UX70h model with integrated cellular capabilities was also developed, but never saw public release.
Sony Handheld Engine Processor
The processor used on the UX series was the Sony Handheld Engine CXD2230GA. At the time of release this processor was bleeding edge, demonstrating new improvements in both capability integration and power efficiency in a single System-on-a-chip.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
