Easy of use - Unity is VERY EASY to use and just works (shaders just work drag and drop, its works in the web, on mac, PC, iPhone and Wii ).
Can you please tell us (if you have tried) what shaders are actually available in Indie version of Unity? I have been going through some forums to even their docs on the site but still haven't found a list or any info on which shaders are Pro only.
What I do know is that you can't get simple stuff like reflective water out of the Indie version without using some 'tricks' (or hacks).
