I welcome many of the new features. It's great for designers who are more technically oriented, though enterable input fields would be nice.
I do wonder how non-technical designers are going to feel. The learning curve is definitely going higher.
I'm worried about the rather pricey per / seat cost. There are far more developers than engineers at most organizations, and this is really going to hurt the licensing cost. Definitely Adobe bean counters flexing its muscle.
Send the ENG a SYN packet, and if they ACK They are an engineer... if they /dev/null your packet, its a DEV.
