We purchased the 2011 Limited AWD with the "premium" package in April. First impressions were that it was pleasant/ unoffensive, about what you'd expect from a minivan. The transmission is surprisingly quick to downshift for passing and shifts smoothly. However, the cheap materials, especially the fake wood (which they should get rid of and stop pretending it's fancy!) and the shoddy stitching on the leather, are very disappointing. I recommend getting the LE and save $20k to upgrade your kitchen or buy a Miata. When I got a tire replacement (see below), a lug nut was cross-threaded and ripped the bolt off. I have not had a major problem like some, but these are a sign of poor quality!
Roominess, surprisingly quick to downshift (good thing for a heavy minivan), plenty of cup holders and plugs, puddle lights, the keyless access ("Smart Key") system works very well and seamlessly (most of the time).
The run-flats are a bad idea -- they are slightly less comfortable, cost a lot, cannot "limp" very far, and nobody seems to carry one when you are far from home. The interior materials and the stitching of the leather need to be upgraded to be more fitting of the $40- 45k price on the Limited.
