Enjoy your new WRX. My buddy has an 07 that he has dropped some money into over the years. It's pretty quick, reliable, and comfortable -- and it handles well in every type of weather.
You'll get haters, but anyone who knows cars will hear the boxer rumble and smile.
Also lol @ the posts saying you're taking a huge downgrade. Anyone who has been behind the wheel of one knows that it can be just as fun, especially in the parts of the country where you get four seasons.
Ignore the idiots telling you to get out, too. Once a Z owner, always a Z owner!
