Really depends upon your local conditions. I live in San Diego where the major tv stations are broadcast inward from various different directions (which makes indoor directional antennas not universally workable unless you're okay with constantly manually rotating it as you go through channels) and here it isn't uncommon for people to live in valleys which make even giant roof-based antennas an iffy proposition. We don't have Aereo here yet, but when/if they do expand here I'd probably get it.
