prostoalex writes "British Internet provider Telewest Broadband is testing a system, which allows people to attach specific smells to their e-mail. It works with air freshener cartridge that one plugs into PC. The technology is developed by a US-based company Trisenx, which features the products and pricing on its Web site. A 20-channel serial port device costs $269, the same price for optional software package allowing the user to author specific smells. The replacement cartridges are $48 each." They're hardly the first attempt at adding smell to the computer experience. Digiscent didn't work out so well.
