To the last point, I have a tiny Bluetooth mouse. Not much bigger than the single AAA battery that powers it. I don't know how I managed to use laptops without one before. (Usually with a full-sized wired mouse, come to think.) I also prefer a traditional keyboard and large screens and so I normally use a desktop. But if you need portable, you need portable.
