Good non-clicky soft keyboard preferred
At the age of 67, millisecond delays in key activation do not matter, quiet operation with low activation pressure and travel are preferred for comfort. Simple white backlight to make the keys easy to read without distracting from the content on the display is also desired. The money spent on bling, I would prefer to leave in my pocket.
(In my youth I used what must have been one of the worst mechanical keyboards ever devised on an ASR33 teletype - the activation pressure was well over 1 pound per key!! The nice soft keyboard that came with a VT220 (the LK201) was still one of the best keyboards that I have ever used. (The LK201 also set the keyboard layout that has been used ever since in desktop PCs.))
Biting the hand that feeds IT
