I use a Laptop and it does have a PP port that works with Mach.!! . . . . . BADLY and UNRELIABLY.

To use Laptop and have a stable working system 100% NEEDS a motion controller. The advantages over the PP make it well worth the money alone and the convenience of using Laptop for me is ideal.

You will have nothing but trouble and wasted time if you pursue a PP Laptop.

Edit: A motion controller also means you can use Mach on 64bit windows machine has well as the most basic Laptop.!
