Pro's/Con's of Web2

"Web 2" is not something I am familiar with, I have always used Apple Mac computers, which is what I am using right now. In my personal opinion, Windows computers have never been the way forward and will never be too reliable. My Macbook is a few years old now and is still working in perfect condition. The web browser which I use is Google Chrome or maybe occasionally Safari. Internet Explorer (aka Web2) is seen as a standard type of browser on Windows computers, I cannot see many benefits of this as to me I cant get on with it. I never have been able to either, HOWEVER, I can also see various benefits, some being the fact that it has developed learning games with children, this benefits everyone as children see it like playing a game whilst subconsciously learning. To me personally, Google is the driving force in the internet world and one day Google Chrome will be something used as standard. It's safer, more efficent and easier to use, its also compatible on all computers, unlike Web2. Thanks
