That's absolutely fair enough - I love that there's a variety of options out there for everyone, and I'm never going to criticise someone for finding what works for them. I guess my point was more about the statement that there's no need for customization if the OS is well-designed - to my mind, there may be no need for customization for many (or perhaps even a majority) of users, but there is for some. An OS that tried to serve all niche needs without allowing customization would likely be a confused mess - and yet, for those users, having their niche need served can be extremely important.
