The Dell Streak is a Google Android-based tablet device that Dell first showed at the Consumer Electronics Show in January.
The Carphone Warehouse said the unlocked device would cost £429. However, it is also available on a £25 or a £35 per month tariff. The more expensive tariff includes unlimited calls and data.
The handheld computer is powered by a 1GHz Qualcomm Snapdragon processor and features two cameras: a webcam in the front that could potentially be used for videoconferencing, and a 5Mp camera on the back with dual LED flash.
The Dell Streak also offers support for micro SD cards up to 32GB and will operate over both Wi-Fi and mobile networks.
