EO
The EO was an early commercial tablet computer created by AT&T, released in April 1993. Officially named the AT&T EO Personal Communicator it was more similar to a large personal digital assistant, and competed against the Apple Newton. The unit was produced in conjunction with the Matsushita, Olivetti and Hobbit chip, created by AT&T specifically for PDAs. They also contained a host of I/O ports - modem, parallel, serial, VGA out and SCSI. Perhaps the most interesting part was the OS - PenPoint OS from Go Corporation. Widely praised for its simplicity and ease of use, the OS never gained widespread use.
