The Microsoft Hardware Team has had a Twitter account — @msfthardware — for just over a week, and they are wasting no time in using the micro-blog service to tease the release of a new product. Yesterday, the company tweeted: “‘Don’t be so touchy…flat is where it’s at.’ We’ll share another glimpse of our upcoming product with you tomorrow.” And today, this image of the corner of some unknown piece of hardware was published by the Microsoft group. Speculation is running wild on this one –personally we think it is some sort of multi-touch accessory like the Magic Pad — but no one knows for ceratain. What do you think it could be?
