I use middle click to paste all time and it's one of the reasons I bought only laptops with 3 hardware buttons on the touchpad so far. How does middle click work with the kind of touchpad on the XPS?

Linux' "Select to copy + middle-click to paste" just saves a lot of time, and has the extra bonus of being a clipboard parallel to the one accessible via traditional copy-paste shortcuts and GUI menus.....
Many people select text using the mouse, then reposition the cursor using the mouse. It's convenient to then insert the selected text using the mouse — the entire operation is done without touching the keyboard.
But it's not 100% reliable.
When I'm not using a mouse, I mostly prefer shift-ins... since the hand is already on the keyboard...
