A very unique tablet concept called HiLo has been designed by Roni Margolin that incorporates a material felt case that also doubles as a keyboard. The main tablet is a 10 inch OLED that links to felt keyboard via Bluetooth.
Inside the felt keyboard case the electronics for the keyboard would use hot pressed embedded circuitry with keys located on the outside as shown in the gallery after the jump.
The Bluetooth case concept is definitely a great idea and I wonder how long it will be before we see manufactures trying to replicate the concept in some fashion for already existing tablet devices currently on the market.
