That is the advantage of modular devices. If you want something, you can literally make it yourself and slot it into the system. If you fall into the camp of just wanting to buy something that works perfectly out of the box, can you really claim you fall into the camp of the 'people who get excited at the phrase "modular laptop"'?
I want something I can't get somewhere else. Being able to make my own modules is cool but there's simply not enough slots to even match my current ultraportable, let alone give me room to experiment.
