MB Air in combination with apple tv 2 and time capsule

Hi there,

Is an Air 13,3 (1.8 Core i7) in combination with an apple tv 2 (with xbmc) and a new time capsule a good combo to have a flawless mediacentre / network?

I ordered this mac Air and now looking into the possibilities to have a nice mediacenter / network setup.
Already searched the net but mostly finding posts about older airs, apple tv and tc's. Some of them not very positive as in the tc in combination with the air being slow etc.

What advise can you people give me in this?

Any input is highly appreciated!
