I found that the interface difference between Infinite and Complete to be quite annoying.  The "classic" Vue interface can be quite annoying at times.  I also like the "widgets" better in Infinite. I really don't understand why the difference between Complete and Pro has to be so dramatic.  Vue Complete isn't a cheap software for most hobbiest, so it's not like we're being given a huge price break.  They could give the hobbiest a break and let us have the better interface--after all that has nothing to do with the higher end functions that would only be used by CG professionals.  The interface isn't a big enough reason for me to shell out that much more money for Infinite; especially since on my systems in the past my ability to use Vue was much curtailed by not running a 64 bit OS with lots of Ram (which I remedied now).
