The ease of day-to-day apps such as Microsoft Office, especially Word and Excel is unparalleled. If you are into DB and work in place that has MS SQL, MS SQL combined with SQL Studio is a very powerful feature. IDE selection is somewhat better because you have more options available -- things like Visual Studio (even for non Microsoft programming languages) are available.
If you go down Linux route and you need GUI, a portion of your time would be consumed by hunting for and finding analyzing options available for you on Linux -- for GUI stuff, Windows seem to be default.
In my opinion, if I am buying a non-Apple laptop, unless Microsoft rolls out a Linux distro with emphasis on GUI and which they will support and develop, I won't bother with Linux as my default OS on my machine.
