Re: +1 about the GUI ...
"It can be configured" unfortunately very often translates to "must be configured, as the presets are abysmally bad". A lot of Linux distributions, Linux UIs, and Linux originating apps suffer from it. GIMP is a prime example. (Interestingly enough, the styles in Word are another good example. It's not just on Linux...)
Now, if a user sets out to configure, one realizes that configuring GUIs and GUI elements is actually quite hard work to make it good. Which is why a lot of users flock to somewhere where this hard work has been done by professionals. Which often means having to pay cash.
