What's not to understand? This happens almost everywhere in everyday life.
What I don't get is that the trolls aren't interested in ever buying, let's say the X1000, yet they regularly return to say the same thing they've said before in most of their posts.
Admittedly I think there's a pretty small chance that I'll be buying an Amiga / Amiga-like thing at any point soon, partly because I just built a new PC, partly because my computer needs (apart from games) are pretty minimal, partly because I would have to get really passionate about a new product and its price and development state (the X1000 demo is what is on my mind here) to be reasonable, but I still hope that something will come which ticks the boxes I'm interested in, because I liked the original Amigas so much.
I don't frequent Amiga.org as often as I did about 4 years ago, partly because I feel it's mostly a waiting game for what I'm interested in. So if I have so little to say because of my very-part-time interest, then what has someone who isn't ever going to buy, say an X1000 or its successors, got to say on such a regular basis?
It reminds me of an argument I had when I was about 7 with another kid, about which was superior, the A500 or the C64, he was adamant that he was right, yet I argued with him so much until, I think a teacher took me aside, and kind of said "what's the point in this? do you really think you're going to change his opinion?". For people to so regularly troll on threads with comments like "it's not a real Amiga, they can't have that name" (are they expecting the second coming with clouds parting and an idealisation of Commodore speak unto them?), or "it'll be a load of crap anyway", etc., makes me think that they haven't learnt a simple lesson or two that I learnt with I was SEVEN YEARS OLD.
