Ok before everyone gets carried away with the "slattern" analogy I think a lookup on
dictionary.com is in order. First of all it has nothing to do with makeup or beauty. The definition I was going for was the most common ie:
slat·tern n.
An untidy, dirty woman.
You see under the conventional definition one has to go out of their way to be untidy and dirty.
The point being, like it or not, most people respond to things that are attractive. If an application or OS is pleasing to someone's eyes they have a tendency to look at it more, instead of flinch away. It's the primary reason there's windows. A lot of stuff can be just as easily done in console mode...but it ain't as purty.
If you care to narrowly define things to their absolute functionality then that's fine. But the truth is for most consumers, of anything, the eye has to be pleased first before they consider quality.
And if you notice for the most part, with almost all shareware offerings there is an attempt to make the application look attractive.
That's just good marketing.
Computers and the web are no longer the sole domain of geeks and techies, as the internet becomes more consumer driven aesthetics will become more important as more and more companies try to get the attention of more and more consumers.
personal feelings aside it's inevitable, and I would rather just try and keep up to date and enjoy whatever benefits the new technology brings. And learn the pitfalls sooner than later.
