Everex Systems is displaying a version of its low-cost CloudBook laptop at the CTIA Wireless 2008 trade show in Las Vegas that connects to US telecom operator Sprint Nextel's Xohm WiMax wireless broadband network.

The company is offering live WiMax demonstrations using the CloudBook Max laptop at the show, but doesn't expect to start selling them for another year. The laptop will also connect to Wi-Fi 802.11b/g networks and can upload or download data wirelessly via Bluetooth.

The laptop includes a GPS receiver as well as a built-in 2-megapixel webcam. Up to 2GB of DDR2 DRAM can be added to the CloudBook Max, and it can carry a hard disk drive as big as 80GB.
