There is nothing wrong with a little bling, or updated "modern" looks, just so long as they are not forced on the user and don't interfere with well-established good work habits.
In other words, bling should be optional for those who want some.
Some like strictly utilitarian, never-changing work environments so they don't have to think about how to do things with the computer. It is all second nature, and the user can get on with his work.
Others like things a little more "interesting" and get bored seeing the same old thing day in and day out. Some people like to constantly experiment with different ways of doing things.
It's all good as long as it's just appearances and the underlying functionality is intact and those who wish to can continue working as they have been without having to undo anything. That is, once again, the bling should be optional.
And individual. Anyone who wants to trick out his or her desktop can do so now. Those who don't want any of that should not have to undo anything.
I personally have a fairly staid desktop. Different desktop images for each virtual desktop, usually a pretty picture of a pretty woman (nothing X-rated, but they sometimes make my daughter roll her eyes :), with weather and system monitor on desktop 1.
I don't get on my computer to admire a desktop.
There's no need to argue about anything here. TDE allows prettyfying already. Different themes, different icons. Whatever.
Can't we all just get along? :-)
