I drove this model with the manual when it came out in the fall. I too thought it was an excellent vehicle. I think this car is ideal for those who like to have the most features they can buy along with a sporty drive. If you are looking for more performance you have to go for the VW GTI which in base trim is about the same price, it definitley has WAY less features, but the performance is superior.
Two problems I have with the Mazda 3, one is that they only offer the 2.5L engine in GT (top) trim, they used to offer it in the middle trim. The other major issue I have is the manual is not cheaper. Which means they are charging you for wanting a manual, as pretty much every other vehicle offered today the manual is $1,000+ cheaper, plus when you go to trade in the vehicle you know they'll use the lack of a automatic as a way to reduce what you get.
