Brando is now offering a Wireless Multimedia Flexible Keyboard. Made of silicone, it promises to be strong, silent, indestructible, storable, portable, water resistant and water proof. Roll it up and take it with you and when you need it, unroll it, plug in the USB RF (about 10 meter range) key and away you go. It features 18 keys for multimedia functions and weighs only 273 grams. It is available in four colours: Black, blue, pink and white.
Unfortunately, it requires both an available USB port and Windows 98/2000/Me/XP so Windows Mobile devices need not apply.
The Brando Wireless Multimedia Flexible Keyboard is available for $29.00 USD directly from Brando.
