Your Dutch must be different from mine (i.e. Flemish ). I don't recall ever writing those in Dutch.In Dutch, you don't need any special letter frequently, but you do need ... â, ê, ô, œ and ç every now and then
Well those are of course mostly used for loan words like enquête, œuvre, façade, and so on. Or names like François. But I guess such words and names are more common in Belgium than in the Netherlands.
The "wrong" here is the categorizing people which means to say one group is more than another because of something. "Lusers" as you put it versus "Powers". All may be purchasers once or many times and all will use the product or they won't. That's not the error in thought here and has nothing to do with how simplistic the GUI will be for the skillset of the person staring into the monitor. What is is one set is devalued over another because of the inferiors inability or desire to learn.
I'm not saying that power users are superior and lusers are inferior. Many people I know (e.g. many of my family members) are lusers, and there's nothing wrong with them and I don't consider them inferior human beings for that .
Sometimes it's good to have an interface / programming language / hardware design / whatever that is designed so that it prevents you from shooting yourself in the foot. But sometimes that is too restricting / cumbersome / inconvenient if you know what you're doing and you want to do it efficiently.
Of course it's best to have the best of both worlds if possible. E.g. on the Pyra keyboard we will probably have 3 shift keys: left, right, and shoulder shift. Now there are only two standard scancodes for shift, and I think it would be a bad idea to make two different keys produce the same scancode. For a regular user who just uses those keys as shift, it does not matter. But for a power user, who wants to remap keys (e.g. right shift to compose key or whatever else), it would be limiting to have it like that. So that's why I propose to have the right shift key on the keyboard produce the scancode for e.g. Super (aka the Windows key), and have a default configuration that makes it behave exactly like a shift key. Regular users couldn't tell the difference. But power users get an extra key out of it.
