Well I for one think the accutrigger was an answer to a need, very good triggers too. The old Savage synthetic stocks were horrible. The new accustock looks like a very good idea and from all reports adds consistency to an already accurate rifle. The new barrel nuts are rounded, so less obtrusive.
I say kudos to Savage for pushing things along for our benefit. They are clearly investing money in R&D and not resting on their laurels. Other gun makers would be well advised to follow them.
