Thank you all for your feedback! So I'm NOT the one going crazy ;-)
I don't mind different opinions if they're stated as such in a polite manner. But I do mind what's going on in lots of forums (not here, thanks god!) Apparently anonymity brings out the worst in some people. Or, in other words: People show their true colours when anonymous.
Now, I'm also a member of a german-speaking smartphone forum and in general, people are polite and have a sense of humour. For example, I had to bring in my Lumia 800 for repair (shattered screen after a drop. I could kick myself.) and got a HTC one S as a temporary replacement. As I thought a few people might be interested in a comparison, I started such a thread. So far, everyone is polite in the thread, there are, of course, some friendly jokes (like: Be careful that you stay faithful to your Nokia device, HTC is sooo good)

I hope that my german-speaking forum and wpcentral stay as they are - those are the two forums that helped me a lot when choosing my phone.
@tekhna:
I agree - Aesthetics matter. But aesthetics are, IMHO, a matter of opinion (What's pretty to person A can be ugly to person B and bland to person C) and this should be respected - which is exactly the thing that isn't done by some verge members. Aesthetics was, btw, one of the points that brought me to WP! Now that I am thrown back to Android, I must say that, while I think Android made some progress and the hardware has become much better (HTC one S is a good phone, no doubt about that), I now know why I went to WP. It just works better for me. (t took me one or two days to get used to WP, and even after a short WP usage (4 weeks), Android already feels foreign and I just find stuff very easily there. I also remember playing with a WP in winter - all the moves just came naturally, which was never the case in any other os I used.
Also, Aesthetics are, I think, changeable in most peoples' minds. Have a look at fashion. A new style comes out (say, trousers that are cut in away like never before). First, most people might shake their heads, and a few other people will try on the new troursers, feel adventurous, buy them and wear them. After a while, those trousers might become prettier in the eyes of some of the former naysayers because their eyes used to those trousers. More people will wear them. This goes on and on, until those trousers, which were, in the beginning, shockingly different and ugly to most, become the standard.
I think if MS and the hardware producers play their cards right (Advertising! Make people aware of WP in a good way! Be insistent, be patient!), WP has a change to become more popular. At least I hope so.
(sorry for any typos and mistakes ... English is not my first language and my writing tends to get error-loaded when I'm emotional. There. I said it. A windows product is making me emotional. Jesus. Must be the separation from my Lumia.
