Hmm…iPad 3 supports 802.11n (which has MIMO) as well. Perhaps the Fire HD is still faster, but it seems disingenuous to leave the iPad column blank.

I could be mistaken, but: 802.11n supports MIMO, it doesn't imply it. MIMO is basically multiple antennas (I think).

In real world applications I think the real benefit is increased range. In an office setting, I could definitely see that being useful.

That probably was not against the latest iPad released the same time as the mini.
