During a discussion with friends and colleagues over a meal last week someone commented that he can type quicker on the thumb-board of his Blackberry than on the full sized keyboard of his laptop which both amazed me and got me thinking: is there a market for a usb thumb-board peripheral for the PC? Sounds crazy I agree, but maybe all the people addicted to their Blackberries would find such a device useful? I had a search around thinking that somebody must have already done this, but so far haven’t found anything.
