What does change is the Serial > USB converters that they use. The more expensive ones (>£3) tend to use FTDI chips, whereas the cheap ones use a CH340G or a similar part.
On some platforms you may have to install drivers to make these cheaper converters work, but they were just plug-and-play for me on Linux.
Which might not be a bad idea anyways. The Arduino framework's been ported to STM32 (stm32duino.com), and you can get a board and programmer for under $10.

Q3. Are these actually original Arduino's, then?
A3. We can only officially answer we don't know.
Cheeky ...Here in Brazil, people go for the cheap aliexpress clones to the point where some of our own manufacturers are closing shop. In these cases, strengthening the local ecosystem might be interesting and wiser in the long run.
I believe that supporting local non innovative shops is better than having no local shops at all.
Where can I get one?

Open source projects push our development capabilities forward, and price competition is just another way it does this.
