Hello guys, I have taken up a music production course recently & also I soon plan to get into DJing. I plan to get a iMac for producing heavy duty stuff but need a MacBook for on the fly producing aswell, ill be using the MacBook pro for Djing mostly. Can someone help me choose a decent config of a MacBook pro that will be able to run Traktor & a few other DAW's like Ableton, Cubase, Reason, Logic etc without much lag. This is my first apple computer so i am a bit confused, i've been on windows the whole while. I dont want the retina display macbook pro by the way. I can afford the base model but since it comes with only 256gb of ssd, i am not interested. Also I am bit confused between the 13inch and the 15inch, remember, the main reason is for DJing only & occasional on the fly editing when i travel. all the help appreciated!
