1) Took a few hours to have everything setup. Transition was easy
2) Not that much. I chose heroku because i hate doing sys admin stuff
3) Can't say for this one, scalingo is a PAAS
4) Scalingo will probably be more expensive for starter plans but as you grow it won't be like heroku's horrible pricing
5) Mostly app with no traffic to be honest
By limiting the number of ports they were able to make it even thinner than the Macbook Air. While it can be disturbing not to have multiple port, you will be able to charge and connect an HDMI BUT... you will need an (expensive) adaptator from Apple or a (hopefully cheap) from another manufacturer.
