Laptop recommendations

My son will be a freshman in the fall. I know the laptop requirements (Dell, HP, Lenovo) but do most engineering students have a 2 in 1 or just a regular laptop? I'm trying to bypass the need to have an iPad to take notes and a laptop to do homework & tests so I'm thinking a 2 in 1 may be the way to go. If you're a engineering student (ME) and have a specific SKU, I'd appreciate it!
