I agree with stonegod, but definitely understand evilbob’s point.  Yes, there are people (usually defender types) that want to upgrade the big 3 every chance they get, since that +1 could make a big difference in a fight.  For everyone else though, once you get “something” in the slot, there is less pressure to upgrade it too often.  I mean, if you are a squishy that is hoping not to get hit at all, is upgrading your armor by 1 that critical, or would you rather try and get a utility item so you have more tricks up your sleeve?
 
It also depends on what the upgrades are, I would much rather keep an lesser item that has a static bonus to something than upgrade to an item that adds a 4th or 5th item daily power that I’ll probably never use due to the milestone restriction.
