Microsoft Courier tablet
Microsoft confirmed in April it has canceled further development and production on its tablet project, codenamed Courier, which industry watchers speculated could help drive down costs of Apple's popular iPad. "At any given time, across any of our business groups, there are new ideas being investigated, tested, and incubated. It's in Microsoft's DNA to continually develop and incubate new technologies to foster productivity and creativity," said Frank Shaw, corporate vice president of communications at Microsoft, in a statement. "The 'Courier' project is an example of this type of effort and its technologies will be evaluated for use in future Microsoft offerings." Microsoft has had quite a history with tablets, as you can see in this separate slideshow.
