One way to picture all-in-one: things that normally sit in separate boxes, gathered into a single box. A printer, a scanner and a copier become one machine; a screen and a computer become one machine; a room, a breakfast and a bus ride become one price. The word is really a whole phrase — all in one — tied together with so it can work as a single word.
all-in-one 可以想成把本來各自一盒的東西，收進同一個盒子裡。印表機、掃描器、影印機變成一台；螢幕和主機變成一台；房間、早餐、接送變成一個價錢。它其實是一整句話 all in one（全部在一個裡面），用連字號綁起來當一個字用。所以它既能拿來形容東西，也能直接拿來指那台被合起來的機器。
