I would notice, especially when A) Linux uses a terminal(apt-get/yum)/Package manager to install most applications. B) Not all my USB devices will work, especially some Atheros-based wifi usb dongles. C) Internet Explorer isn't the default browser (I['m use to changing it to Firefox/Chrome) D) Not all my games will work, even using emulation. E) I will be happier to see a lot of my tools for web development are easier to setup/install, and less "looking around" for them on Linux. F) I use gimp on Windows, so not much difference in image editing G) They have crappy unintuitive video editors that I would just rage at.
