I'm sorry but the example you gave for your argument makes no sense at all. Most people here have tasks and daily meetings where these tasks are discussed or at least briefly mentioned (in other words, your "iPad guy" is already there).

If someone is slacking, it is immediately visible. Can you abuse the system by providing fake explanations for why one task takes so long? Of course, but you can do the same whether you work remotely or not, and this can also be easily verified in both cases.
