Yes, I think it would be the boring everyday things that I'd miss the most too. Getting a coffee, making a phone call, watching the news, having time alone.
They must have some interesting footage from the different seasons. This year with Skye taking her clothes off every time something interesting happened in the house that didn't revolve around her so it couldn't be played at family friendly hours and several couples had regular sex in the house too apparently, if you believe the hinting the hm's have made. The cameras would still run regardless even though there is no uplate this year. They had no trouble finding footage other years, I assume this lot were no different. I think I'd be a bit uncomfortable knowing that footage was out there though.
