I think that with HIPS or HIPS style features, there will be those who swear by it and those that swear at it.
It can be a real boost to security but some are so noisy constantly popping up a dialogue window asking the user to decide about this and that when many of the users simply hasn't a clue what they are being asked. The trick is getting the balance right so that it doesn't have a major impact on the normal use of your system.
I too up to date have chosen to avoid HIPS programs on my system.
