According to The Feature, Radixs will show its product on the DemoMobile 2003 conference in California. According the the company's website, the MXI Platform functions on a Single Operating Layer Architecture (SOLA), a technology beyond the multi-layer desktop computing architecture used in traditional mobile devices.
Once loaded onto your mobile device, the MXI Platform connected to the MXI Servers establishes a seamlessly integrated environment that can execute and multi-task full-featured applications, video and audio playback, complete web content and more.
At the heart of the MXI Platform is a powerful engine. This engine manages all user requests and activities, and provides all of MXI’s wide-ranging capabilities.
The MXI Platform offers distinctively unique benefits to users:
Launches operator-hosted applications from the MXI Servers without needing to download or install locally
Executes Palm OS, J2ME, built-in and downloadable applications locally
Plays all multimedia formats supported by the MXI Servers without the need to install new plug-ins
Fully customised skins with sound FX themes
Because their website is quite obscure in terms of technical details and information, and without going into further details, I can only think this is a client-server model, where the MXI platform will be a client hosted on a Palm OS or J2ME mobile device (a smartphone by this description), with a server that will answer requests that can not be processed locally.
Doing a Google Search I've found more references to this platform. One of the source cites "...company officials showed how a laptop computer running on the MXI and acting as a server, streamed office, communications and entertainment apps instantaneously onto the “client”, an iPaq PDA. The MXI has two parts: one is the client OS, and the other part is the server OS..."
Why does it sound like a walled garden description to me? Why companies insist in calling this stuff "OS" when the OS is actually a layer below (the Pocket PC or Palm OS)?
