Some people love all-in-one computers; some hate them. I've been in offices where every station has an iMac, in environments where everyone has a desktop with a monitor, in workspaces where everyone has a laptop, and in hot desk offices.
I always prefer to have what I need in my bag or a hot desk scenario, but for that workspace that makes sense, like a front desk, an admin's desk, or a simple in-room computer, for whatever reason, the best all-in-one computers make a lot of sense.
