Hi! I am a recent college grad with a bit of Graphic design experience and i would love to explore it a lot more. I am in the process of looking into tablets and other drawing surfaces to work with Illustrator and maybe Photoshop as i learn on the way. I have an older Macbook Pro that is running fine, but i would like to be able to have something portable and maybe sketch on for when i go on hikes, but then use as a drawing pad for when i use my Mac? i dont know if something like that exists or if there is a better option. Preferably the cheapest, but somewhere around $500 would be fine w/ a stylus pen would be fine? Thank you!
