Right off the top that would be the Surface models with pen, the iPad Pro with its pen and then off to the Cintiq models like https://www.wacom.com/en-us/products/pen-displays/wacom-cintiq
If you go cheap, I bet you won't be happy.
So I'm looking for a robust and lasting 2IN1 laptop (not a detachable), a window os with 16GB of RAM (because I love opening hundreds of tabs and painting the with hundreds of layers), 500GB SSD storage, a 7th or 8th generation intel core i5 processor, a full hd touch screen (12',13' or 14') with fair specs and pen support, and a decent graphic card (just enough to run photoshop and illustrator), it would be perfect if it's light weight and has good battery life for outdoor use. I want to use it for drawing, photo editing, watching movies and browsing the net. I was hoping you can help me find the less expensive option that fits my needs.
