This is another awesome gadget, made of special Silicone rubber which does not break on any number of times of bending. Also, this mini keyboard has a complete closed structure which makes it waterproof and you can wash it any time with water and clean the external surface, unlike the standard keyboards which are a rest for food and oil from many hands that use it.
It is a strong and indestructible, also portable enough as it can be bent and kept in the side pocket of your bag while traveling. It can be used in any environment, and also the rubber is soft enough to keep your hands at rest, and they do not pain while using it for long time. It has a sleek flat design that one would love. And the keyboard is attached with USB cord to connect with the PC/Laptop/Netbook.
The package also has a PS2 Adapter for connecting with the round socket in a PC, if the USB sockets are full already. But one thing that Mac users won’t love is that they can’t use this keyboard. It is compatible with only Windows 98, XP, 2000 and ME.
The Flexible USB mini keyboard is available for $22 at Brando.

Did you actually try it on a Mac? Almost any PC keyboard will work on Macs (including keyboard shortcuts — just because there’s no Apple key doesn’t mean that keyboard won’t work with a Mac or that keyboard commands won’t work. It’s just using different keys (windows, alt instead of command, option).
It would be helpful to know if it was actually tested with Macs and found not to work as opposed to just being assumed not to work without any sort of test.
