Brendan - this all becomes so naturally evident when you witness the lack of
good technical support for the product.....
and lack of customer feedback and communications....
and lack of good beta testing....
and so on and so forth.
These important "lacks" become a death-march for a high tech company.....
I can hear the drums now.....
