Why is it so many people still use Windows? Why not linux?
Linux is free! Plus it's nice that I can have a nicely featured, not bloated, up-to-date system installed in ten minutes with Linux.
Or, I can run to the store, shell out too much cash for a Windows OS, hope I bought the right version that suits my needs, wait almost an hour for it to install, then have to install all of the drivers, reboot the computer countless times. Then buy a bunch more software...
