Before designing a new program, observe similar programs on Mac &
Windows. Look for an intersection of the most controversial
patterns & reuse them.
Make everything take as many clicks as possible.
Hide crucial details by default.
Repel grumpy people with low contrast.
Make your program look & function like a Chinese replica of a
Japanese tool.
Design an interface with a hypothetical fat manual (that a user
would require) in mind.
Remember that some % of young folks in the 2nd-world countries
can't afford Apple hardware. Design a program that, on the first
glance, should do its job, but that actually miscarries every time
a user tries to use it--the loser must be reprimanded for his lack
of necessary funds, otherwise he won't have a stimulus to improve
his financial well being.
