The communication methods have changed drastically over the last century. Not long ago, telegraph was the only way to get in touch with people around the world. Graham Bell invented the telephone and heralded a revolution in the way people communicated. This lead to a transformation in business practices and some even credit the rise of America to this ubiquitous piece of equipment. But telephone in this modern world is pass?. SMS and mobile telephony are the latest buzzwords. The World Wide Web is the vehicle of modern communication. Is it any surprise that email via PDA is no longer a luxury but a business imperative? The other day, I had been to an exhibition along with my pet laptop in tow. Now, this laptop has all the latest frills and balloons. But do you know what I felt like? A dinosaur. At least that's what my pet laptop looked like in front of the sleek mobiles and PDA. An email via PDA is far easier to execute than a gigantic operation via the laptop. With a nifty keypad creating an email via PDA is a breeze. The main advantage of a PDA is its light weight, small size and sleek looks. It can do all that a laptop can and more. One can have all the office tools which are used commonly like word, excel and even presentations. With Windows CE, Blackberry and some other system software, it is hard to find the difference between a laptop and a PDA. PDA has the inherent advantage that it is designed for wireless operations. We can email via PDA, send and receive data and do a lot more. I would call it the ultimate men's accessory.
