While using the Bluetooth feature, you can run through a lot of advantages to and at the same time and run to a lot of disadvantages also. With about every great technology, there has to be something in there that makes it not perfect. There's probably no such thing of a perfect product. A few advantages and disadvantages of Bluetooth includes the following.
Advantages:
Widely Used: Bluetooth is now really popular and keeps getting more popular as time passes by. It is now widely used across countries and almost by everyone. Companies are taking the benefit by using this in their new and future products to make life much easier for everyone. Pretty much very soon, you will be noticing quite a bit of technology will be wireless due to Bluetooth. As it is already, but most likely it will be more dominant. You can use Bluetooth on laptops, cell phones, music players, headsets, printers and a lot more other products.
Feature Simplicity: You do not need to know much about technology in order to run Bluetooth. Anyone that doesn’t have no knowledge about the new technology can still be able to use the Bluetooth feature due to its simplicity and the ease of use. I think that the simplicity of it and the fact that it's wire free makes it very widely used and utmost popular.
Free of Charge: Best of all, you do not have to pay a penny for the service! It's not an extra cell phone or cable bill that you have to add to your budget. Simply by the technology and you're done! All you need to do is connect it with what you are using. There hasn't been any reporting lately on companies charging a monthly fee or any fee for people to use the Bluetooth feature and I don't expect it.
Go Wireless!: It allows you to stay cord free and do not have to worry about finding the correct place to connect that extra long cord. Avoid having to have a ton of cords wherever you go. You may still need a few cords but not as much as you would without Bluetooth. You can also go to the internet wirelessly with this feature when you're out somewhere outside of your home.
Your in Control: Even though you are able to exchange data across your cell phones, you still have the ability to keep your information private. In order to make a transfer or allow someone to access the files on your phone, you will have to give them access by accepting or rejecting the request through your phone. If you have the Bluetooth feature enabled on your phone and not disabled while using it, others that you may not even know request to send you a file.
Disadvantages:
Battery Use: This occurs mostly on your cell phone but also occurs in other technology such as music players. You're using up more battery power when you leave your Bluetooth enabled on your phone all day. To disregard all this, the best thing that you can possibly do is disable it once you are completed with the transfer. It only takes a few seconds to enable and disable so it wouldn't hurt to disable it once you are done using it.
Bluetooth Internet: Throughout all devices, when using Bluetooth internet, the connection can sometimes run very slow so Bluetooth internet is not highly suggested for all cases.
As you can notice that there are quite a bit of advantages and fewer disadvantages. Overall, Bluetooth is a great thing to be using on all your devices that supports it. You can do so much with it and includes cutting all the cords attached to your devices.

Personal Wireless with Bluetooth
If you already have a wireless network for your computers, you may be very interested in what's coming next. Would you like it if your PDA, your mobile phone, your mp3 player and almost everything else you connect to your computer could be wireless too? It's already a reality...
Personal Area Network.
Using wireless networking with your personal gadgets is often called PAN, which stands for Personal Area Network. The idea is that, in the future, we'll all have laptop computers with their batteries charged and no more need to connect any wires to them at all -- you just place your Bluetooth device near the computer, and the computer sees it and can use it straightaway.
Bluetooth has been around and in-use since 1999, and it's only getting more popular. It was designed to be secure, low cost, and easy to use from day one.
There are two classes of Bluetooth that are in popular use: class 1 and class 2. Class 2 is the most common and cheaper standard, allowing you to use a device that is up to 10 metres (32 feet) away. Class 1 is rarer, but you can still find devices that use it easily enough, and it has ten times the range: 100 metres or 320 feet.
How Does It Work?
Bluetooth is more flexible than 802.11 wireless networking, in exchange for the shorter range. Essentially, a Bluetooth-enabled computer has one Bluetooth receiver installed in it, and this receiver can then be used with up to 7 nearby Bluetooth devices. On the other end, wireless devices do not need to have Bluetooth installed if they support it -- it is already integrated.
Like 802.11, Bluetooth works by using radio signals to create bandwidth. It is not, though, the same thing as an old-style wireless mouse or keyboard, which required a receiver to be plugged into one of your computers' ports, and didn't have range or stability anywhere near that of Bluetooth.
Many computers now come with built in Bluetooth, especially Apple Macs. If you want to add Bluetooth to a computer that doesn't come with it pre-installed, you should probably use a USB to Bluetooth adapter, although internal Bluetooth devices to install in your computer are available. If you have a laptop and a spare PCMCIA slot, you can get Bluetooth cards for that too.
What Can You Do With Bluetooth?
Mobile phones with Bluetooth are very popular, and so are PDAs -- the instant synchronisation of addresses and calendars to a computer is a useful feature. Other than that, almost anything that would usually use USB can be done using Bluetooth, including digital cameras, mp3 players, printers, and even mice and keyboards. If you take a look through the comprehensive list of Bluetooth 'profiles' (kinds of devices that could, in theory, be Bluetooth enabled), it includes cordless phones, faxes, headsets, and even video.
Basically, more than anything, Bluetooth is a replacement for USB: some say that while 802.11 wireless networking is wireless Ethernet, Bluetooth is wireless USB.
Not Just for Computers.
Part of the power of Bluetooth is that it isn't just used to connect things to computers -- it can be used to connect almost anything to anything else, if both things are Bluetooth-enabled and recognise each other.
Mobile phones, in particular, take advantage of this. Hands-free headsets often use Bluetooth to communicate with the phone. Some cars, for example, now have on-board computers that will connect with a Bluetooth phone and allow you to make hands-free calls, regardless of where the phone is in the car (even if you've left it in your bag in the trunk!)
On top of that, of course, Bluetooth devices can communicate with each other. This has led to some people sending messages from their Bluetooth PDAs to others in close range -- not an especially useful feature, but quite fun. This is called 'bluejacking', and the first recorded instance of it was a man who sent a Bluetooth message to another man's Nokia phone while they were in a bank together. What did the message say? 'Buy Ericsson'.
Since then, it has become possible to send images by bluejacking, and it is widely believed to be the newest advertising medium -- yes, it lets billboards send messages to your phone, a practice known as 'bluecasting'. Whether you think that's cool or annoying, of course, is your choice.
