In terms of an object of conspicuous consumption, to satisfy your every whim or just to look pretty or whatever, you can spend as much as you like, spend money you don't really have, it is your prerogative.
Just don't wildly exaggerate the performance benefits in the process.
You just don't get it do you? People are spending on what they want with funds they do have!
Nobody really gives a hoot for your 'Science' when buying a new anything. Mostly their choices are completely abstract. Maybe you don't have the finances to buy the latest and the best kit, perhaps there's an inverted snobbery going on here...
I try and buy the best kit I can afford at the time. A. Because it generally performs better and lasts longer than cheap stuff and B. I like the good things in life, I've worked hard for them, so why not?
You/and or Science have absolutely no place in the criticism of other people's buying choices. The world is a great big mixed up place and that delivers big mixed up choices. That you still maintain this unwelcome point of view, criticism over sympathy will win you no friends. Quite the opposite. Perhaps that doesn't bother you. Like I said upthread, for some, knocking about like a tramp with a home brew haircut is 'okay'. Others would baulk at that picture.
Its called choice. Most people like to learn from their own mistakes, garner their own knowledge about things, even hold opinions different to others.
Thats not snobbery, that's just the human condition.
