just to clarify: the paperweight is completely optional. The primary interface for paperspace right now is a web browser but if you want an inexpensive device to act as a dedicated terminal, you can buy the paperweight.
It would be nice to have a cheap "disposable laptop" that works off a cloud-desktop that you don't need to worry about losing or breaking. People don't buy laptops because they're slow anymore, but because they're physically worn out!
The equivalent of a cheap Chromebook that's like a real desktop with lots of power and runs Windows games and real applications!
In the future, I wonder how you could implement a cloud-desktop that's zero-knowledge a la SpiderOak. That would be the ultimate secure workstation.
