Great post, sums it all up very good!
I have one additional thing you should keep in mind when you think about getting a puppy:

The type of the dog is not just defining the size of it. It also defines its personality and its special needs. A hunting dog for example needs to chase after something regularly. So you have to check if you can satisfy the special needs of the dog-breed you want to get before you get it. Inform yourself and choose a breed that fits into your daily habits.
