Well, I am using this new system from time to time when the regular EPC is down and it is not bad, actually. One issue I have with it is that it does not record full VIN of an old car so when I key in my Pagoda VIN it just remembers 113044. Graphics, descriptions etc. are better.
Also: EPC looked obsolete. especially when you compare it with, e.g. BMW system. Also: EPC had issues with Java editions, was not easy to set up. And the biggest issue for me was transferring parts to Webparts to generate order (but this one may just my issue, it may work differently if you have a shop set up). In the new system you click on the part and click add to basket.
