As always, most of the posts ranting about the iPhone essentially say the same thing. "I've never used the iPhone, but I'm sure the lack of feature 'x' makes it completely worthless". 'x' may be cut-and-paste, MMS, or any other minor detail -- my favourite being the "broken Bluetooth stack", which must be the most ludicrous reason ever for not liking anything, let alone an iPhone.
I've used the iPhone and really like it. Lots of people, I'm sure, have used the iPhone and don't like it. All perfectly valid opinions. However, adding a comment that says, "I don't like the iPhone, and I don't see why anyone else does either" when you've never used one is simply wasting everyone's time.
I honestly can't imagine ever reading an article on the N95 and thinking, "I know. I've never used this handset, but I think I'm going to write a comment outlining what I suspect its failings might be, and explaining why I'm not going to buy one." Seriously, why would I think that anyone else would give a f*ck?
