Good laptop for plasticity?

I've been out of the laptop market for a while, but I need to get a new one. Don't need it for gaming just modeling in Plasticity and maybe Blender. My main requirements are good battery life and a decent screen. Will mostly be using it when traveling. I'm a bit tired of lugging around my 12 year old Asus brick. What would you suggest for memory size and any specific laptop recommendations? Thanks
