I would be interested in this as well. I've been using the URC MX-700 and MX-800s since about 2003, but with some new equipment I finally got stung by not being able to upgrade the MX Editor software since 2006. I'm a bit disgusted by URCs stance towards end users who purchased their remotes before they changed their software policy.

In any case, I'm now looking at the Harmony line and would like to hear comparisons with the older URC remotes such as the MX-700 and MX-800.
