people will find all sorts of what seem like rational reasons for buying stuff when in reality the purchase is purely driven by want and can and not need.
For example, smokers will rationalise smoking. Rolls Royce owners may say they only bought it for its quietness but do you really believe that is the driving force (pun intended) behind the buying decision? Personally I don't and I rekon Roger must know an awful lot of Rolls Royce owners for his statement to have any validity. It's as rational smoking. You buy stuff, any stuff except food, out of pure want rather than need. That is why advertising is so effective. It is a purely psychological reponse driven out of conditioning. For most of us anyway, unless we actually engage our brains which is a rarity. And most of us, even those who like to think we have engaged our brains can rationalise anything to suit our wants rather than our needs.
For what its worth I don't think dust removal system is a necessity. Regular cleaning will suffice and you'll have to clean it anyway as you don't want your camera full of accumulated dust which is easily shaken up. Might be a nice to have though and it will save me lots of post dust removal except that I'm going to have to check the whole image anyway if doing a careful job which kind of kills that little rationalisation.
So why are you celebrating Christmas? If the answer is because you are a Christian then fair enough. Everyone else celebrating will give all sorts of reaons none of which have any validity except to suit themselves.
Highlight 1:
Look at it this way.
Most people have cars.
If you can afford one, and want a large, comfortable, quiet car, why not an RR? I
think I'd prefer a Bristol, but as I can't afford either, any answer would be meaningless.
Not, however, quite as meaningless as the statement that the only reason to buy an RR is to show off. No doubt some do. Maybe most. But the RR owners I've known -- which is not many -- tend to regard them as nice cars. The point is, I've known
none who buy them to show off. 'Advertising'? Not in most cases. Knowing other RR owners; driving an RR; counts for more than advertising. I've also had at least two friends who ran RRs as tools of their trade (undertakers on the one hand and wedding cars on the other).
A lot of it comes down to whom you know personally, and how they present their arguments. I'm not pretending that my sample is statistically significant, but I'd still say it's more significant than a sample of zero -- unless you personally know people whom you are sure bought them to show off.
Highlight 2: well, food... and clothing... and heating oil or gas or wood... and some way of cooking your food... and, actually, if you live in the country where there's no public transport, some means of private transport... and...
Cheers,
