A permanent access to all your emails... You dream about it? Blackberry phone did it. The BlackBerry is a wireless handheld device introduced in 1999 which supports push email, mobile telephone, text messaging, internet faxing, web browsing and other wireless information services. Same size as a PDA, with a mini keyboard, BlackBerry device allows you to receive and reply to emails.

How does it work? Connected to a cell phone network (Cingular BlackBerry, T-mobile BlackBerry, Sprint BlackBerry, nextel BlackBerry and verizon BlackBerry), terminal BlackBerry regularly query the email server of the user. When a new email arrives, the terminal signals it. The user can then read the message and reply. innovation comes from the fact that synchronization of the emails with the messaging server is real time through the cell phone network it is connected and it supports both gsm, GPRS and UMTS.

Of course, BlackBerry service is more specifically dedicated to companies. The devices are very popular with some businesses, where they are primarily used to provide email delivery to roaming employees. To fully integrate the BlackBerry cell phone into a company, the installation of BlackBerry Enterprise Server is required.

But the popular device BlackBerry that allows reading emails using cell phone network is forbidden in some companies. Indeed, some security experts fear about communications being intercepted. However, Research In Motion (RIM), editor of BlackBerry, claims that all the traffic is encrypted from start to end by the Blackberry servers installed in companies. In fact it has the exact same security level as a traditional VPN if correctly configured.

A Blackberry handheld allows users to fulfill their need of communication but also give them the feeling of control that a phone conversation doesn't offer. More and more professionals often work in mobility situation and need to permanently be connected to computing system of the company.

According to a recent study, one third of business users show signs of BlackBerry addiction almost similar to those of alcoholism. Some people even use the ironical term "crackberries" to name the phenomenon. Also, most users are supposed to get BlackBerry devices to enhance their productivity but their constant attachment to email make it hard for them to concentrate on other things when they are out of office.

The professional Blackberry is a "all in one" terminal, phone/PDA/messaging, which design is optimized to allow users to manage emails on the go and to access various applications. The original BlackBerry device had a monochrome display, but all current handsets have color displays.

Most BlackBerry devices is equipped with a full QWERTY keyboard, The ease of keying in and sending not only emails, but also sms, is particularly practical, even if they do not have a BlackBerry.

However, the BlackBerry has no memory extension, no 3G compatibility, no camera and not much style. What is more, multimedia functions still remain low compared to other Symbian or Windows mobile. That is until today with RIM unveiling its first and brand new multimedia phone dubbed the new BlackBerry Pearl. But still BlackBerry devices depend on mobile phone service coverage and are not wifi compatible unlike similar handheld devices that are on the market now.

RIM BlackBerry is increasingly integrating instant messaging into their new devices and software. RIM offers its own proprietary BlackBerry Instant Messenger, but also offer a yahoo Chat and Google Talk clients and probably an upcoming BlackBerry MSN Messenger client.

According to RIM, BlackBerry PDA is used by about 5.5 million users worldwide.

Blackberry is used by almost 3 million users in America. Some sources say about 1 million government employees are regular users. Canada is another one of the key market of the company.

While including the usual PDA applications such as address book, calendar, to-do lists, etc you can always download more BlackBerry software like games, ringtones, themes, webclient and other applications.

Whether you are a beginner at golf or a professional, you will want the golf ball that suits you and your game best. You will also want to get the best golf ball for your money. This is where golf ball reviews come in handy as a reference tool.

Don't allow yourself to be swayed by what you see your friends or fellow golfers using. First, they may have been golfing longer than you have. Secondly, they may have an entirely different technique than what you have. There are many good golf ball reviews online, in magazines or stores that will be very helpful. It is wise to remember that the most expensive balls may not be what you need. The top-of-the-line name brands that you read about may not be the best for you either. More expensive is not always best- just more expensive.

Golf balls consist of two major types: wound or solid. The wound balls are the conventional balls that have been around for years. The solid ball came into play in the 1980's. Originally, golfers were of the opinion that the solid golf balls offered little control of spin and performed poorly in general. They were used to the wound ball. Technology has now advanced to where golf ball reviews will show the increased popularity and use of solid balls.

Beyond the two basis types, there are one piece, two-piece and three-piece balls. The one piece, made of Surlyn with dimples, is the basic ball for on the driving range or just starting out. You won't get much distance, but they are very durable and inexpensive, which makes them great for practicing. Two-piece balls have the core and a strong covering. Due to the high restitution covering, you will get great distance and durability. Manufacturers are now able to make them "softer" which contributes to greater control. Golf ball reviews have shown that these are very popular for the every day golfer on the course.

Three-piece balls, wound with a liquid center or solid, allow the more experienced golfer the control he wants. The backspin is very good and there is good distance and height. These are more for the experienced golfer who is able to "control" his shots with spin and distance.

There are also four-piece balls, but they are new on the market. They are made of a soft Urethane, are durable and great for distance.

You will be able to choose if you are looking for spin or feel golf balls. Golf ball reviews will help you decide which ball is right for you. Low spin golf balls will lessen the amount of side spin when you shoot, therefore the ball will go straighter in the air. It may not go as far in the air as you"d like, but with less spin it will roll more when it hits the ground. This is a good ball for player that is unable to get a long drive. A mid spin golf balls is the ball most suitable for all players. It combines both distance and feel. High spin golf balls are made to increase the spin when it"s in the air and go farther. They are used a lot by golfers that hit right to left with a draw.

Firm feel golf balls are used for distance, and will feel hard when hit. They are used if distance is more important than spinning onto the green. It's a very durable ball and will go many rounds. Mid feel golf balls act similar to the mid spinning ball in that it is the most suitable for all players. It combines distance with being easily controlled on the green. Soft feel golf balls are balls used by many professional golfers that are able to use spin on short shots. It is not a ball for beginners. It is easily nicked or damaged due to the soft cover.
