I recently went on a shopping spree on Dealextreme.com and I ended up ordering a bluetooth keyboard, since I couldn't bear to fork out S$98 for an Apple Wireless Keyboard. The package has arrived and here are some pictures.
You get what you pay for, so the keys are not as tactile and responsive as my Logitech Illuminated Keyboard or even the Macbook Pro keyboard. It may be because I'm not used to it though. From what I can see, it's almost exactly the same layout as an Apple Wireless Keyboard, although on the product page, the photos show a windows key rather than a mac command key, but it works the same.
It is rechargeable, compared to the Apple Wireless Keyboard which requires you to insert 2 AA batteries. However, it doesn't charge using a regular mini USB port like most devices. Instead it actually uses an Apple 30 pin dock connector. It even includes a cable in the package. No idea why this particular design choice was made, but it's good since I have these cables lying around everywhere.
Setup is easy and fast. I managed to connect it to my iPad, Macbook and PC. Still yet to connect it to the Playstation 3 and iPhone. Will try that later. If I'm not wrong you would have to re-pair it with a device after you connected the keyboard to another device. A minor hassle but I think this is the same with all Bluetooth keyboards. It also includes a mini CD with drivers, but you probably wouldn't need it. I notice there are 3 lights on the top right of the keyboard, but I think none of these lights is the capslock light. Kind of weird, considering the first time I turned it on, all 3 lights were working. Pressing capslock does not activate any light.
Overall this is an pretty good product, especially since I paid much less than an Apple Wireless Keyboard for it, S$40 exactly. It may not be made of brushed aluminum, but it looks good and performs decently. Here are more pictures.
