Wow, this under-power argument is old...and unfortuneately totally inaccurate.

I'd agree with that statement. I test drove a Rubicon last week and it felt very similar to my YJ, TJ, XJ.
I think it would be a great family hauler, if you know what you are buying. Will it handle the highway better than a GC, no. Will it be as convenient as a minivan, no. For what it is, it comes as close to all-around utility as you get, and the top comes off.
That being said, I still won't buy one until there are more used ones on the market and price has come down. I'm too cheap.
