There is absolutely nothing wrong with this, you're completely right. What is wrong with it, however, are two things.

First of all, it is in the wrong place. Complaining about purchase of a product is fine, but you generally don't go and do it somewhere only tangentially related. As an example, if I bought a Dell PC, and it was a piece of crap, I'd generally go talk to Dell about a refund, or a repair, or whatever. I wouldn't go to a Dell end-user forum, regardless of whether or not there might be the occasional Dell employee from another division wandering around the same forum.

To move away from the example and back to the real world - maemo.org is not a Nokia feedback channel. It's an enthusiast community around (primarily Nokia) devices, and as such, the people here aren't likely to have a hugely enjoyable time on threads like these - and nor will the person posting originally - given that their feedback is not going in the right place, and as a result probably won't get the response they were looking for, if at all. (Of course, I'm assuming good faith here, but I'm a nice person.)

So: Nokia Care, Forum Nokia, Nokia Conversations, or any other official Nokia medium (perhaps best of all: physically writing to them) is likely to be a better option than venting frustrations on a random, tangentially related at best, internet forum.

Second of all, there is complaining, and there is constructive complaining. Going back to my earlier example, when I ring Dell and ask them for a refund, they're generally not going to take "your product is a piece of ****" as a reasonable reason to offer a refund (unless they are feeling really generous).

Again, back in the real world - the OP didn't really give any value to the subject he was writing about. "It's crap and I should have bought XXXX", while obviously paraphrased, is not far from the point of the original post - and obviously - is totally worthless, even to people who might be able to do something about it.

Thanks for your points, though.
