Linux is not as comfortable as Windows... User interface, application compatibility etc. in windows is better than Linux..... I personally like Windows.. it does'nt mean that linux is not good, it depends on what context you are considering.....
That's subjective and untrue. Only major applications like Photoshop or Windows Media Player are incompatible with Linux because they're specifically made for Windows and/or Mac. However, there are alternatives. Thus, http://alternativeto.net/\
And the interface in any given Linux distro can be changed. Example: some don't like the new Ubuntu GUI/desktop environment, so you can replace it. Same with anyone else with any other Linux distro if they happen to prefer a different desktop environment
P.S. If a system absolutely needs to specifically have Photoshop or something like that, that's when you dual boot- that's what I did with my system for a graphic design class.
Linux is still general more compatible with your hardware (depending) and allows your Linux OS to sit side-by-side with your MS or Mac OS and typically has better support for hardware.
I had to go through a ton of crap , just to get a compatible audio driver on my laptop... Almost any given Linux distro I had on disk had support for it (I tried the Live CD for 3 different distros and all of them had better support). Plus Linux is FREE, uses less resources and is more lightweight, and, as mentioned, generally has better hardware/driver support. Just a few of the reasons people prefer Linux.
So it's hard to say that Windows is just better than Linux OS just because it has more market share, which really only happened because Microsoft was standing with a corporate giant (IBM) when they started out.
