Maybe if I could use it onscreen. Trackpad-only, lot lower chance, but maybe. There was a company that modded MacBooks & MacBook Pros, modbook.com, to make them tablet computers with stylus. Unfortunately, they haven't released anything new in years, and haven't even released a retina MacBook Pro mod. They had a Kickstarter a while ago for one, but looks like it's just vaporware. Shame; it would've been cool.
