UK-based wireless provider British Telecom (BT) has revealed plans to create a portable tablet PC, but chief executive Ian Livingston is playing down allegations that the device will be a competitor to Apple's iPad. The unnamed device was shown off at a demo in London, but specs and other details are not yet known. Livingston says the device is meant for use around the home and not be carried around like an iPad, suggesting it may only have Wi-Fi and lack 3G data access.
