I was only looking to update the firmware in thinking that the unit may have improvements similar to what you get with BIOS upgrades on a PC. Subsequently, no real reason, except I was hoping for greater or improved functionality/performance. Same with the S/W "E". It is a very good basic software, but could use many improvements which I have seen on more expensive models. One feature I really liked with a higher end S/W viewer was the ability to track how far back your recordings went based on date. In that version, the date numbers would go opaque if data was not available to be viewed. Thanks for the update.
