Awesome. I have no interest in using this, but the more pressure on Apple / Dropbox to up their storage quotas, the better.
I agree with wanting the 1TB option to be cheaper, but I'm finding fewer uses for Dropbox unless I switch to the business plan, which doesn't make sense. However for a family, you get 5 users for 15/mo and unlimited space. I'm still trying to figure out the downside to the business plan.
And I see that they have support for RSS and other feeds which might work for some of the integrations I want to do.
