I love the familiarity the Command Center would give any iOS user. Having a access turn off notifications and a built in night mode (similar to f.lux if you've used it) makes this a really great addition to my everyday tools.
I've tried this.. A bit buggy to spent 10 dollars on. iTunes Cover art does not load. It never resolves my IP. Network is always at 40% as is the User/System, both stuck at 40%. Great idea I guess... but it's not there yet :)
