I remember hearing about Bluetooth around four years ago when I was working at a web design shop and one of my managers was touting it as the next big thing. While the manager is long gone, Bluetooth has stuck around and it seems to have finally started catching on now. Logitech’s jumping on the technology with a release of the Cordless Desktop MX for Bluetooth, whew!

If the set looks familiar, it’s because the design is almost identical to the Cordless MX Duo that’s wonderful for gamers who crave a wireless solution that won’t hold them back. Comparing the two products physically, the only thing I can really see different is the color scheme. The Cordless Desktop MX for Bluetooth is an off blue instead of the traditional black.

Instead of the traditional RF technology to communicate with the base, the set uses Bluetooth to provide better range and less chance of interference with other wireless products. The cradle also doubles as the Bluetooth hub and lets you connect other devices such as PDAs or phones that are Bluetooth enabled. There are motherboards that are starting to include Bluetooth built in, but those without it can use the Cordless Desktop MX for Bluetooth to be Bluetooth compatible. Range is around 10 meters, or 33 feet and it is a universal standard. In the future when products such as printers and controllers implement the Bluetooth technology, you’ll be ready to take advantage of them with the cradle/hub.

Connecting the product to your computer is done through a USB port and if you would like a PS2 port. As with the Cordless MX Duo, the connection to the power cord is on the rear of the USB plug. I wish there wasn’t the big power brick on the plug and it was separated from the prongs as it does take up a lot of room and can interfere with other power sockets nearby. Companies need to get rid of this design and help free the space near your power sockets.

The keyboard’s slim profile, known as the Zero Degree Tilt, gives you a comfortable reach to the keys. Shape-wise, the keyboard’s layout is the same as a regular keyboard. I’m more partial to the ergonomic design though so I’m hoping that Logitech does release the same setup with that type of keyboard. Looking at the keyboard, you can see a whole mess of buttons and dials included with the regular setup. I’ll go clockwise from the left and touch some of the keys in this review. On the left side, you see two buttons and a dial that’s the same as a mouse wheel. Of course, the dial functions the same as a mouse wheel in web pages and more. You can do such things as adjust the volume, scroll through your favorites, and zoom in and out. One of the side buttons opens up an input box to enter a URL to surf to. The other side button allows you to go back a web page. With the two buttons and a scroll, you can do some casual browsing if you don’t need to click on links. Unlike the Cordless MX Duo, the keyboard for the Bluetooth version uses 4 AA batteries instead of 2. Not sure if because it uses Bluetooth that it needs more juice to last as long or if it would last longer with four batteries, but the keyboard does take more power. I do like the tactile feedback from the keyboard. It’s silent and gives you a good response when pressed.

The MX 900 is in essence, the wireless version of the corded MX 500 and the Bluetooth version of the MX 700. The design of the mouse is nearly identical with the exception residing in the absence of the cord and the difference in weight. The MX 900 requires 2 AA batteries to be inserted into the unit, adding quite a bit of weight. This actually works out to be an advantage. The added weight to the mouse makes the entire unit feel much sturdier than the corded mice.

The MX 900 features rechargeable batteries so that the consumer can be spared the chore of having to purchase batteries. The charger itself is in the receiv...
