Laptop for connecting to CNC?

[MCmec]

Well after Neale's advice I purchased the Dell Latitude E7470 Laptop,I think I will need it to download up-to date software for CNC use as my Mac's are running old systems that do not download some of the current software. Al I need to do now is find a, not too costly, good used CNC router, Buy a cost effective new one or try building my own! Either way I now have more options than before.

If you are using a Laptop then you will definitely need an external motion controller and ideally an Ethernet-based one. USB is too flaky and even worse on a laptop which uses heavy power management and not all can keep the USB turned on all the time. They will shut USB down when ideal which isn't good for CNC.
