I think different folks are looking at Iphone 5 from different angle. The Android folk that posted in forums tends to be a group that is more technical in nature and want the latest and greatest. It is important to them that smartphone has the latest toys. Whether someone use the toy or not is not an important issue. How many smartphone users will be using NFC day to day? But it is a must have if someone buy the next phone by comparing the features. For the normal customers, something else is more important. They looks at the things that affect their day to day use of the smartphone the most. You can see the divide in the online review. You see a minority of reviewers who review by checking off features (i.e. cpu speed, size of ram, NFC, screen size, micro-sd ...) and they give Iphone 5 generally low market for miss checking all the marks. Majority of the reviewers up to this point focus on the general design of how light, how thin and how comfortable when they use Iphone 5. A few of them actually comment on how the "cheap" the competitor feel. The plastic back cover for S3 was not a problem before Iphone 5 show up. But now Apple raise quality of material issue with their product and ask customer to make their choice. And the size of the phone also become a design issue. Before Iphone 5, bigger is better. But now all of a sudden hold the phone with an average size hand become an issue (read: woman as target audience since their hands tend to be smaller). Design a phone thinner, lighter with smaller foot print but yet keep the speed and battery power competitive is not a easy engineering task. Apple has to bring in the in cell touch (and pay for it through higher cost) to cut the thickness by only 0.5 mm.
Now that thin and light weight is in.. Let's see how long it will take other competitor in the space to respond. Racing to the latest feature is a no win situation manufacturers and customers. Manufacturers have the lead for 2 to 3 months and the next guy will have a phone with better feature list and the sales of the phone will drop to the floor. User will feel like they have to upgrade every few months. It is a lose-lose proposition. For manufacturer like Samsung and Apple, the challenge is to build a smartphone that can last a while that both the manufacturer and user can recover their investment in the phone before moving on to the next one. And I think Apple is creating a phone that can stand the test for a couple years. i.e. no one will feel bad about having an Iphone 5 in the next couple years when newer phone with more features come along. And that is a good design decision in my book.

iPhone 5 vs Samsung Galaxy S3 - Opinion - Trusted Reviews
"Samsung's great white (well, pebble blue and white) hope for 2012 has an all-plastic finish that uses a flimsy, ultra-thin back cover. This is the one part of the phone that has caused the most criticism, as it doesn't make it feel all that much like a device you should be spending ?500 on, even if in practical terms it's just as tough."
