Agreed. It seems crazy if you just look at the numbers, but the fact that these are smaller than a typical bicycle really makes difference. They are hugely easier to maneuver up and down stairs, especially if you have to go around a corner. Take up less space parked. They are much easier for farmer's markets or other times when you have to get off and walk your bike among a crowd of pedestrians. Easily adjusts to different height riders, so it's a great bike to have around as a loaner.
Here's my old one that I sold a while back:
The rack is a cut-down rear rack made to fit OK. The basket is a letter tray from Office Depot zip-tied on. If you use a front rack like this that's another plus of the mini velo -small front wheel means massive cargo room on top of your rack before the load interferes with the handlebars. Because of the front-rear weight balance and low-trail geometry these bikes do great with front loading, too.
I don't have a great pic of it, but I also had at one point mounted up a Civia Pizzeria porteur platform rack. Here it is carrying a large mess bag and some veggies from roadside stand:
Honestly that rack is a bit large -almost sticks out past the front of the tire and kills some of the small-bike-size advantage.
As I said, I've since sold this orange one, but have also just picked up a nice black one and I'm in the middle of upgrading it. Will have the saddle and stem/bars/levers as above, but have some new fenders and other bits and bobs.
