Given all that's offered, I think $7/mo is a good price. But a matter of 3 bucks quintuples the number of devices it can be installed on...
Still too expensive. $30 cheaper for 1/5th the number of seats, dumb dumb dumb.
You're still better off going with 365 and sharing the cost with a couple of friends or family members.
Not a bad strategy, as long as the bill gets sorted out evenly. ;)
