In response to Apple’s millimeters-thick stainless steel keyboard, Microsoft’s latest announcement is the Bluetooth Mobile Keyboard 6000, their thinnest keyboard ever.  The entire keyboard is only slightly thicker than the AAA battery that powers it at the back. The stylish keyboard has Microsoft’s familiar ergonomic curved layout.

Something missing from most laptops these days is a number pad. For anyone who uses numbers with any frequency, an external keyboard becomes a necessity. The downside is that a number bad adds a great deal of bulk. Microsoft solved this but making the keypad a standalone product that comes with its own carrying case. Pair it to your computer when you need it, and stow it away when you don’t.

The Bluetooth Mobile Keyboard 6000 will retail in October for $90, while the number pad will be $45. Certainly not the cheapest keyboard set ever, but probably worth taking a look.

It’s a taller, narrower iHome clock/radio/iPod dock. Only this time, it has Bluetooth on board. This allows you you to make wireless speakerphone calls from your iPhone, cell phone, PDA, etc., right from your alarm clock. It also lets you beam your music from any Bluetooth-compatible product (like your laptop) and play it up to 30 feet away on the iP47.

We finally got the chance to play with the iP47, and we’re impressed. The Bluetooth works as advertised, and phone and music playback sound great.

The calls were surprisingly clear over the unit, and you can even make calls using the remote control, leaving your iPhone or whatever plugged in and charging. A tray also pulls out of the unit with a full alphanumeric keypad. You can also plug in anything that’s not wireless via the line-in jack.

At $150, it’s an investment, but weigh the features and decide for yourself.

One is small and loud, and the other’s got Bluetooth.

They’re still in the concept stage. Here’s what we’ve gathered so far — mind you nothing is set in stone.

The iH69 iPod Computer Speaker System with Computer Sync, in addition to being a mouthful, is a compact, versatile solution for all your dorm/desktop/bedroom audio needs. It docks, charges, plays and syncs your iPod and computer audio (or any other audio source for that matter) and if it follows company trends, will sound as good as some of the larger computer speaker options out there.

It’s being marketed as a clutter-reducing sound solution. The iH69 also has a remote control and is built on 20-watt, 2.5″ Reson8 speakers.

iHome showed the iH69 concept at CES in January. Look for it later this year in the $200 range.

For a more robust choice, the iP47 looks like it will be a sick desktop solution with built-in Bluetooth to wirelessly stream your audio from a cell phone, PDA or computer. It also works with your iPhone and has a speakerphone/microphone combo that lets you take/make calls right on the device.

Like we’ve seen with other iHome clock/radio options, the iP47 also features dual alarms, AM/FM radio, snooze, etc.

iHome may have a few more tricks up its sleeve later this spring. Stay tuned.

It supplies emergency power to nearly any small, portable device, but not in that disposable, one use, drug store special kind of way. The rechargeable lithium polymer battery will fill up your cell phone’s gas tank three times before the GearJuice runs dry.

GearJuice will charge your Blackberry, iPod, iPhone, PDA, Bluetooth headset, cell phone and nearly any low-power device that takes a USB or mini-USB source. The device detects how much juice you gear needs and outputs the correct voltage.

The product can charge itself from any USB device — so you can just plug it into your laptop or desktop computer. It comes with six attachments, including iPod touch and iPhone and mini-USB connectors. Some models come with American and European wall plug adapters, but my model didn’t come with an AC adapter — which I didn’t mind because it’s actually much easier to charge the GearJuice right off my computer.

One small complaint: the GearJuice should have come with two full-size USB dongles. If you’re charging the device off USB, you aren’t left with a spare cable to go right ahead and charge up your cell phone or iPod at the same time. To this effect, GearJuice won’t turn your laptop into a power inverter.

The device itself charges up in a few hours from a dead, empty battery and IOGEAR says it will hold a charge for six months.

There are a variety of specialty adapters you can buy for GearJuice including the full-sized AC adapters and Samsung, LG and Motorola phone packs if — somehow — your phone doesn’t fit any of the included connectors. (When are all cell phones just going to charge and sync via mini-USB?)

Do yourself a favor, don’t throw out or lose the spare connectors. Put them somewhere where they won’t get lost or tossed. You’re probably going to break, lose or replace your cell phone within a year, and you’ll be crawling around trying to find the other connectors.

GearJuice is compact, comes in a soft, velvet carrying bag and priced right at under $30 on most websites. I approve.

The patent pending 29 LTD BT is the first-ever CB radio is aimed at making communication easier and safer on the road by bringing your cell phone calls wirelessly into the CB unit.

This isn’t your normal Blast Magazine uber gadget, iPod, MP3 whatchamacallit, but the nerd in me squeals at the sight of this baby.

“With Bluetooth technology, the 29 LTD BT allows drivers a better way to have phone conversations on the road because calls from a mobile phone are synched with the CB radio. A noise canceling microphone allows calls to be heard loud and clear, even over a noisy engine,” Cobra said in a statement earlier this week. “Incoming audio is routed through the radio’s 5-Watt CB speaker making it easy for the driver to hear the caller. The Bluetooth feature also gives drivers the ability to answer and terminate calls by pushing one button on the CB microphone, allowing drivers to stay focused on the road.”

The new 29 LTD BT also has the standard CB complement including access to emergency channel 9, and tactile controls to allow the driver to feel where the dial is in its rotation without taking his eyes off the road.

The new unit also offers 4 Watts AM RF power output, the maximum amount of power allowed by law. (Insert Tim Allen grunt here)

The 29 LTD BT will be available this summer for $189.95.

They come in a wide variety of packages and configurations.

In a nutshell, there are three main Bluetooth devices, the TX, the RX and the F1.

The TX sends audio, the RX receives audio, or you can go with the F1 — stereo Bluetooth headphones.

The Cerulean F1 wireless stereo headphones reach 33 feet, and they allow you to to plug-in to any auxiliary audio source or iPod-compatible audio system and listen to it.

They are designed to with with traditional iPod docking platforms, and the TX and RX don’t require any batteries because they’re charged by the iPod and Dock-compatible audio device. You can use them with non iPod products, but you’ll need an external power source and audio wires.

These are great but expensive toys. A set of TX + RX or F1 + TX will run you upwards of $150. They sound great, however and are sleek and stylish on top it it all.

Overall, if you’re willing to put up the extra dollars, iSkin’s Cerulean line is one of the best, most compact Bluetooth devices I’ve used. It removes the wires, but it’s versatile enough to be used away from the traditional iPod application.

Take a look on the iSkin website.

Though there are some considerations to make — this isn’t a good idea for an iPod or another portable MP3 device. The way the Audio Transport works is that it lets you plug a set of earbuds/headphones into a Bluetooth receiver. So there are still wires to worry about, and there isn’t really a point to using this for an already portable device, unless you plan on leaving your iPod on a desk or table or somewhere stationary while you walk around the room. Just not sure why you’d do that…

Anyway, the Audio Transport does give you the ability to listen to any audio source from up to 33′ (feet) away, and the sound quality is pretty good, with SRS “Wow” surround sound technology.

If you’re looking for a Bluetooth device, $50 is the average for cell phone solutions. The IOGEAR Audio transport, at the same price, gives you that and the expanded capabilities.

Features:

• Enjoy music wirelessly from Bluetooth-enabled computers, PDA, MP3/CD players, and more

• Comfortable to wear behind-the-neck style
• Convenient built-in rechargeable battery for up to 6 hours play time
• Connect the Bluetooth Audio Transport to your stereo system to wirelessly listen to music stored in your Bluetooth audio devices
• Avoids interference with other wireless devices and does not requires direct line-of-sight
• Class 2 device compliant with Bluetooth 1.2 specifications Headphones Audio
