Honestly, get a decent laptop and not that crap.
My last MacBook lasted from 2008 until this January (and it actually still works, I just wanted a new one). It was heavily used, it had cracks, stickers on in, dings in the aluminium case, some keyboard keys were blank, totally scratched.
It worked in direct sunlight, in total fog and on a freezing ice bar.
I had more DJMs fail on me than that laptop (as it never failed me).
Also this topic has been discussed to no end and there is a search function on the top of the page 🙂
