I have so many gadjets at my house it could get a little confusing; but I do enjoy my time-capsule. The cool thing about it is having 4 RJ 45's built in. I have it connected directly to my modem and I have 1 computer, directv, xbox and playstation connected. This helps with my gameplay on multiplayer. I use the back-up rarely, but it has all 4 of my family computers back-up to it. Then I have 5 individual cloud accounts that back-up pictures and preferences for each of my family members. All iphones share one cloud account for music; so everything is uploaded and refreshed to avoid double purchasing of shit.
Then I got apple tv in 5 rooms (master, living, 3 kids rooms); which have a audio and video receiver in each room. That way everyone can still enjoy the iTune movies purchased or sharing the music.
Then I upgraded my cable modem to the 20mb speed. What I know is when all my kids are home and two are gaming, one listing to music and my fiancé surfing the web; there is little to no lag. I love it!
