I just stumbled upon a blog post by Marco Arment called "Fanboy theory". Since I'm having this talk quite a lot in my personal life I thought it might be a good idea to reference the article here.
Though I'm being called a fanboy quite often and I'd even say myself that I'm one (because I don't think it's disrespectful or derogatory, but that's a whole other story) I try not to force or influence anyone to buy products they might not make reasonable use of. If you don't want, need, or like what I'm using just get something different. I'm making a lot of jokes about being a fanboy as defined in Marco's article but I'd suggest that you don't take that too seriously.
