/3/ - 3DCG

Any good laptops to model on?
I don't need to worry about rendering, I do the majority at home, but I'm gonna be out of the house a lot from now on, I wanna keep modelling/animating while I'm on the train commuting, or on work lunch-break, so preferably not a big machine.
I'd also ask about laptops I can use Unreal 4 on, or Mudbox, but I dunno if that's getting a bit too ambitious.
Either way, I'd need something small, but capable enough to model without chugging.
