What do you mean usage for internet and OS is pretty much independent of internet and it is your browser that is depended on your browsing experience.
Depends really on your computer, if your running a old computer that has 256mb or memory than you probably dont want to be using Win7 or Vista. Though normally if you have a decent computer, doesn't really matter. Like what shabbir said it more of which browser(Opera!!) to use, and slowness of internet could be your connectivity.
If you are looking forward to Windows, Windows 7 is the best option for now, however, if you wish to have any other, I think Mac is the best.
I like windows 7... however if you'll be just working online and no much local application to run then I suggest you use ubuntu as this is more resistant to virus.
it depends on your hardware, software specification and configuration and internet connection. OS like XP n 7 are much better. hopefully useful.
Hey friends, Thank you for yours valuable suggestion, The best Microsoft Windows operating system to use depends on what its intended use will be and who will be using it. There is no specific operating system which can be called "the best" overall, and since most current operating systems share most common and advanced features there is much debate on the topic. A few of the most popular operating system, their pros and cons, and some of their best uses are described below. Thanks a lot again Carly Fiorina
