I don't think that they are pointless. At least no moreso than is buying say an A4 over an Accord or Mazda6. You are getting a more refined, better equipped, better driving vehicle. Whether that is worth the additional cost or not is very subjective. Otherwise I would agree that you should cross shop the segment.
We recently cross shopped the Q3. We really liked it, but ultimately decided that a Toyota RAV4 AWD Limited with the Tech package was a better fit and value for our needs (wife's daily driver, expected to last 10 years/200,000 miles). The Q3 was undeniably a nicer vehicle, but the long term reliability of the Audi was my biggest concern. If buying an Audi, I would want a CPO for the longer warranty and the Q3, at least as of a few months ago, was still too new to find CPO units.
