Review: Apple Wireless Keyboard (aluminum)
With the green light flashing, the keyboard is paired the same as any other standard Bluetooth keyboard. Under Mac OS X, the keyboard shows up as a device under the "Setup Bluetooth Device" assistant (below top), and you are prompted to type in a pairing number (below bottom). Once pairing is completed, the keyboard just works. It can be turned off by holding the power button down, which lights the LED for about four seconds and then turns off the LED to indicate the keyboard is now off. Turn it back on, and it automatically begins working without having to pair it again.
Keyboard range appeared to be limited to about 20 feet in my testing, although Apple says 30 feet on its website. As with any Bluetooth device, usable range will depend upon sources of interference such as metal objects or other wireless devices, including cordless phones and WiFi. When trying to type from a distance, keys seem to stick down like thiiisssss before it loses signal completely. In normal operation, the keyboard worked well, but Bluetooth does not work for long distance wireless, such as typing to a presentation PC from across a large auditorium.
The F Key Mystery
The new keyboard also sports a series of new key assignments. Rather than using the default F9 thru F12 keys for Exposé functions, the new keyboard assigns Exposé's "all windows" hotkey to F3 (it is F9 by default), and similarly maps the Dashboard trigger (usually F12) to F4. Both keys have unique icons that haven't appeared on any keyboards before (below). F1 and F2 are assigned to screen brightness, as they commonly are on Apple's notebooks.
F3 thru F5 are commonly mapped to volume controls on Apple's notebooks, but the thin new aluminum models remap audio controls to the other end of the keyboard. It also adds playback controls for back, play/pause, and forward to F7, F8, F9 (below). These playback controls work for the foreground application. That means if you're listening to music but working in iPhoto, hitting the advance forward button doesn't skip to the next song, but rather advanced to the next photo. Hitting the play icon starts an iPhoto slideshow, and other applications can interpret these keys to mean whatever they wish.
Depending on whether you expect them to only control audio playback (as similar keys on Windows keyboards typically do), or whether you like the idea of having a multifunction set of buttons that work in different applications, this is either a frustrating problem or a great feature.
F5 and F6 have no icons, while audio volume controls are mapped to F10, F11, and F12 (below), next to an eject button.
These controls seemed to work inconsistently. When I paired the keyboard to a MacBook Pro, the keys worked as labeled (for example, F4 brought up Dashboard), while the MacBook Pro's own F4 continued to work as a volume key. The wireless keyboard's actions therefore did not match keyboard settings in Mac OS X. Holding down the Function key on the keyboard had no effect on how the F keys worked either.
When I paired the keyboard to a different desktop system using a Belkin USB Bluetooth dongle, the keyboard paired properly, but the keys did not work as marked; instead, the F keys all worked as they were assigned by Mac OS X. That system also failed to properly display the keyboard under System Preferences' Keyboard section, which is supposed to indicate its battery level. The keyboard worked, it just failed to show up (below).
This puzzle was only solved by consulting the user manual, which indicated that new software needed to be installed. The keyboard does not ship with a CD (it also requires Mac OS X 10.4.10, so you'll have to have an updated version of Tiger running to use it). Instead, the manual tells you to run Software Update. Unfortunately, my system did not find any updates when I did this. I had to search for the update on Apple's site. Sure enough, Apple released a Keyboard Software Update 1.2 in early September. I had to manually install it.
Once installed (it requires a reboot) my battery level indicator worked correctly (below top), the translucent Bezel Services "keyboard disconnect" graphic was updated to match the thin keyboard outline (below middle), and a new check box appeared in System Preferences (below bottom).
The new control in the Keyboard & Mouse settings allows you to choose between using the keyboard keys as they are marked, or to use the default F key settings, which can be configured as desired. Mystery solved.
The other change on the new aluminum keyboards is the departure of the Apple logo from the command key, which now features the word "command" along with the Mac propeller icon (below) used for command in menu listings. The story behind that change was related in the article, "How Apple Keyboards Lost a Logo and Windows PCs Gained One."
Somewhat oddly, the Option, Shift and Esc keys are not labeled with their menu icons. Apple only puts some of these icons on foreign keyboard layouts, leaving new users to guess at what the glyphs might mean.
One feature I'd like to see added requires new software support on the iPhone: the ability to pair the phone to the Bluetooth keyboard. Imagine using the duo (below) as a hyper thin traveling companion for taping out notes. Unfortunately, while the iPhone now supports Bluetooth pairing with a computer, it does not yet advertise support for any Bluetooth profiles apart from hands free, which used for the Apple Headset Adapter we reviewed in July: AppleInsider | Review: Apple iPhone Bluetooth Headset.
That means no keyboard input for the iPhone, no stereo Bluetooth headphones for music, no Bluetooth sync, support for printers, nor any other features, at least not yet. Until then, Apple's Bluetooth keyboard makes for a stylish way to work without cords, or to control a PC or Mac from across the room.
With a cheap USB - Bluetooth dongle, the Apple TV would also make a keyboard candidate, particularly if Apple expands upon the device with other applications beyond wireless iTunes access. The ultra thin, ultralight keyboard would pair well with the unit to turn a living room widescreen HDTV into a web browsing, iChatting new general purpose Internet device.
Apart from asking more of systems that might make use of this keyboard, it's hard to find faults with anything in the keyboard itself. It's nearly identical to the MacBook's keyboard, which is quickly becoming one of the most popular notebooks available. Unless you're looking for something big and heavy or cheap and flimsy, the $79 Apple Bluetooth Keyboard represents a very well built, attractive wireless keyboard at a reasonable price.
