I have a lot of indoor plants now and I don’t have an indoor watering can.  An outdoor watering can rains over a great area, while an indoor has a single spout to prevent a mess indoors.  I don’t have one, and have been using things that are less then satisfactory, either too small or they drip when pouring.  I started to wish that I had an indoor watering can, but I would rather not have to spend the money on it, or find a place to store it.  Then I thought about a tea pot- little spout, already have two, and have to store them, holds a lot of water- perfect!
