I have seen Microsoft Windows 7, as it is currently dubbed, the other day as I installed in in a VM. What I saw did nothing for me that my operating system choice already does in a better way with less resources and has done for at least 2 years or more.
The Linux based platform has come a long long way since it first appeared. The kernel is now more robust than it ever was and the desktop much more user-freindly. The whole experience is quite simply much better than it was only a year or two ago.
I install many operating systems for people I know and for people of people I know who I don't know but now do and many friends and friends of friends etc. Then there are the installs for family added to the mix. Some have a preference for Microsoft while some prefer a Linux distribution, others ask for a dual boot setup so they "can test the waters". What they mostly all want is something "that just works for what I need to do" on the system they have and a Linux distribution fits that bill perfectly in 99% of cases.
In years gone by getting a Linux based operating system to play nice with some of the more estoic hardware available could be a challenge but as more and more hardware companies move away from proprietory software standards to a more open standards world this challenge has been almost eradicated. There still remains a stubborn pocket of hardware makers that are going against the flow but as more and more machines are installed with a Linux based operating system they will eventually wither and die away or join the growing band of hardware makers previous mentioned. Installing a Linux based operating system now is as easy, if not easier, than installing a Microsoft created operating system.
Microsoft still hold the top spot in users of their creations but not because of any other reason than they buy their way onto machines sold, thereby creating a false sense of people bying their flagship software operating system. Some call this the "Microsoft Tax". Myself just finds in an annoyance that is swiftly eradicated and replaced by something I call much better but that fact, of course, does not suit everybody and I now appreciate that fact. Another fact I now appreciate is that not everyone wants to rely on someone else to keep their machines running. Microsoft Windows, of any flavour, and a Linux distribution both need someone that knows what they are doing to help them get to grips with the operating system installed be it a Linux based one or a Microsoft based one. What I find now is more people want to become more self reliant in this area. Of course, there are, and probably always will be, some who cannot survive their operating system usage without someone else who knows what is what and why something happens when it should not.
A Linux based operating system now can be set up in such a way as to keep both sides happy and in some cases can be setup so that it can automatically do everything itself, save for those who are most likely and determined to kill whatever is in front of them on their monitors
If you run a Microsoft based operating system or a Linux based operating system both have the option of running another operting system within their chosen one. These are called Virtual Managers. So. There is a way to run the opposite without the need of a dual boot setup or removing the installed operating system.
So, go on. If you run a Microsoft operating system or a Linux based operating system give the opposite one a go. There is now nothing stopping you installing one of the mainstream Linux based distributions, but remember it is not anything like MS Windows so all the brain washing that that has given you is useless. It is a new and slightly different way to get the same things done. As long as you remember that basic thing then you will enjoy the freedom it offers you.
The major difference between the two option is that of cost. Most Linux based distributions are free while all of Microsoft flavours cost anywhere between 80UKP and 400UKP. If cost bothers you then there can only be one choice. Go for it.
