How would you change Apple's Time Capsule?

Now that Time Machine's all buddy-buddy with AirPort Extreme's AirDisk feature, we can see the demand for Time Capsule sinking considerably. Still, Apple's own NAS drive / WLAN router combo has likely found its way into quite a few households, and now that you've had a chance to back up your life a couple times over, we're interested to see how you'd tweak things. Are you really pleased with the interface? Are transfers snappy enough? Want a little more freedom with how you're able to configure things? Would you rather it not function as a substitute for a portable stove? Let's be honest -- Time Capsule's a pricey piece of kit for what you get, so feel free to let Cupertino know exactly what's keeping you from being absolutely satisfied in every respect.
