Brazil has a very protectionist economy. In the last 20 years (roughly), for every multinational enterprise that manifests some interest in settling on the country, lengthy rounds of negotiation are taken, mostly for discussing tax incentives.

I understand your point of view, but I really meant to focus on the position-guessing mechanism. It brings some problems, such as low "batching power" and great reliance on the widgets positioning.

IMHO, GUIs lack of conciseness, because of the big screen area demanded to properly represent all the necessary interaction elements, and consistency, since actions taken by the user (that unconciously performs bidimensional pattern recognition at each interaction) are not easily reproducible by a machine. It would demand that all windows are the same size, and positioned at the same place, they were when the user interacted first.

Obviously we could compare that with a CLI, that demands a proper construction of a syntactically correct commands. Though it is true, commands and settings can be properly stored (in a history file or a shell script) for future execution.

It is important to remember that CLIs were the oldest way to interact with a computer system of both. It was made by programmers, to programmers. But, still today, they prefer to have a concise and consistent way of accomplishing their tasks. Guessing positions in an Euclidean plane based on less-than-descriptive tips contained on pictograms and labels isn't something we can call "concise" and "consistent".

It is just an example, and it has more to do with the drawbacks of running virtual machines as a replacement to native systems (as pointed by adonoman) than with SUA itself. I knew since the beginning it was a terrible example, though, but I wasn't able to think anything better.
