The surface tablet only has a cpu, no dedicated gpu, thats why I mentioned the book. That does have an option for a dedicated gpu but it's just not quite strong enough.
Honestly I don't think you're going to find a laptop with a dedicated GPU and stylus support.
Stylus support on Laptops is VERY uncommon. the only company I can think of off the top of my head is Dell. (but those Don't have Dedicated Styluses) and just recently Microsoft's Surface Book. but that is way to pricey for what it's worth.
THey're pretty tough. I've used them before and thats your only AIO option. What are you going to be doing? If you got 2 SSD's for it that laptop would be up to spec.
Edit: And I can garuntee you if you put linux on it and used XFS or JFS that it would be blazing fast.
Yeah, I've been looking for a decent amount of time and haven't found anything. I just thgouht it wouldn't hurt to ask if anyone had seen one. The only option I have seen is get a laptop/ mobile workstation then buy an external wacom monitor but that adds bulk.
I'm going to be using TIA Portal, Solidworks and various other less demanding engineering software, so I'm afraid linux is out. Plus both run best with faster single cores, particularly solidworks.
