How would you change Canon's EOS 50D?

If the Nikon D90's questionable 720p movie mode did nothing for you, or if you're a self-proclaimed Canon fanboy through and through, there's at least a sliver of a chance you bit on the EOS 50D. Now that you've had a solid month to flex that shutter finger and pore over the results, how are you liking things? Experiencing a huge dose of buyer's remorse? Absolutely elated with the low-light performance? Did you find enough extras to warrant the upgrade from a D40? We're just looking to hear how you really like / dislike Canon's latest mid-range DSLR, and more importantly, how you'd do things differently if given the keys to the company's R&D lab. Get to spoutin', won't you?
