People who aren't blinded by marketing gimmicks, I suppose. Not a 920 hater, I just want to try both of them before I buy. Spec wise, the phones are practically identical.
It's time to get passed the ois and carl zeiss crap... the camera just isn't that good. I already have gloves made to work with phones so what's left, oh, when was the last time you looked at your phone and said "holy f**k this screen wont refresh fast enough to play a game!" I'll bet never.
I am not going to sit here and tell you which phone to buy, but what you call gimmicks, plenty call features. I could say that the 8X's gimmick is that it is thinner and lighter, as that is something I don't care about, but you obviously consider those features, which is completely acceptable.
As far as the screen is concerned, you get deeper blacks, much better view-ability in sunlight, and of course being able to touch use the phone with any gloved hand. I have tried a couple of those gloves that allow you to use smartphones while on and can say that, for me, they are God awful. Not to mention they aren't very good looking, but I tend to prefer a leather glove, so this is all personal preference. Will the L920 be better? Tough call... I haven't tried it.
As far as storage is concerned, neither have removable storage capabilities. You are stuck with what you buy. L920 gives you 32GB for $99. The 8x gives you 8GB for $99 and 16GB for $199. Off contract price of the L920 is $450, while the 8X off contract is $$549/599. I think this is a point of no contest. One literally cannot argue that the 8X is the "better" phone here. I suppose you can say you don't care about storage. Well ok.
As far as the camera goes, I am not sure what "not that good" means. It has been put up against some of the most highly regarded smart phone cameras on the market (iPhone 5, SGSIII, HTC ONE X) and outperformed them all in nearly all situations. In areas where performance could improve, it was stated by all reviewers that this could be an easy software fix. Nokia seems to care a LOT about their camera. I have no doubts that they will clean this up. Even so, what this means is an already leading camera has the opportunity to be even better.
As far as refresh rates go, no, nobody has ever said that they need more for gaming (as far as I am aware). But as an overall experience, fast refresh rates are just "prettier", for lack of better words. They are also easier on the eyes. Media (video)consumption should also be more enjoyable. For the person that is looking at their phone for hours throughout the day, it is going to be a generally better experience.
The 8X shines with it's amplified audio. I have yet to hear a comparison or see anyone really talk about it, so it is tough to make a decision here. I have heard a lot of people call the beats audio tech a gimmick as well. I am not going to call it that. For those who really enjoy music and use their device heavily for that purpose the 8X has the clear advantage.
So if you choose the 8X, I won't talk you out of it. I won't even say (or think) you are making the wrong decision. Because the beauty of Windows Phone is that we are given a choice between a handful of devices and are able to pick the one that best suites our own lifestyle. Likewise, I expect you to extend the same courtesy to the rest of us users and not lash out about how you think every feature that doesn't matter to you is a mere gimmick. It is childish, it is rude, and it doesn't add to the discourse of the thread whatsoever.
