I pulled the trigger on a open box R40 for quite a discount, so I will have both the Mx-450 and the R40 for awhile. I was thinking about doing a review of the two and how they compare.

I know the mx-450 has the archiver app which can also update the database and firmware, but I really wonder how often URC is going to update the firmware on a 4 year old remote, anyway once you have the codes for your hardware, it's not a big deal to program these remotes.
