Do you know the one thing that caused me to abandon Linux and get back on the Windows band-wagon when I got a new Thinkpad? There is absolutely zero PDF editing/viewing software for Linux that will compare with Acrobat Pro, Foxit Phantom or Nitro Pro.
That , and the fact that there is nothing on Linux that absolutely needs Linux. Nearly all open-source software in the Linux world also runs on Windows. OTOH, there is plenty of commercial scientific and engineering software that is either available only on Windows, or has been optimized in such a way that it works better on Windows. This is often due to the graphics card drivers. I just recovered from a 2-week fiasco with AMD drivers because some linux developer pushed a broken kernel (pci_ignore_hotplug removed!).
I think it is time that people admit that as of 2015, there are several use cases where Windows is just better to have installed rather than Linux. In fact, I'd go so far as to say if you have to install just one operating system on a computer, most definitely install Windows. As a computer literate user , you are less likely to have to fiddle and run into roadblocks with Windows.
