I would agree with Malsidious – with a couple of other points.
In a DJ laptop, what I want is:
– Decent processor – that means Intel i5, 3rd gen or higher, at least dual core and a processor speed somewhere above 2.0GHz.
– 4GB Ram – the more the better. I run 8GB and have never had any issues. Bear in mind that this is sometimes not upgradable (mainly in apple hardware but watch out)
– Decent Cooling. A DJ booth is often a very hot place and many laptops will start to slow the processor down if they get too got – not ideal during a DJ set. The measure of “Decent” will change depending on where you live (hot/cold) and where you gig.
– High(ish) res screen. Screen resolution is more important than screen size in my opinion, although I wouldn’t go smaller than 13″ – I use 15″ at 1366×768 and which it was higher resolution sometimes – this is where Full HD or Better-than-HD displays come in handy.
-Backlit keyboard. Many higher-end laptops come with this and it is really useful in an often dark DJ booth..
That’s it. If you are a video DJ, you may want a higher-end graphics card in there as well but if not then it is unnecessary..
