Look for thunderbolt 3 or better yet 4 for the ports if they have them. Supposed to be wicked fast, if port speed is important to you.
I was waiting on 2-1 laptops to include them standard before buying again. Some ehave them but lack other features I want right now. I did buy an acer 2-1 but the pen issue with them is horrible, and their customer service is the pits. I sent it back., got a galaxy tablet instead jutz until new 2-1s come out with the feature I want
