Reply to MB Air Vs MB Pro 13" for machine and rekordbox

So I was believeing of buying another laptop in my set up, to take some load off of my 2010 mbp 15".
It will be used primarily for two things:

1)Running machine software, synced with the other laptop (running traktor), to create instant loops with the step sequencer.

2)Running rekorbox connected via ethernet with cdj's in order to utilise the bigger screen which makes track search easier.

P.S. do you believe the 11" macbook air is capable of doing both of the above? (trying to minimise backpack size)

Thank you in advance.
