Heh. I think people are just currently spoiled by choice. (Which is a good thing). People act like if a company doesn't have Apple-like success, it's some sort of failure. Even though the marketplace would actually *BLOW* if everyone got Apple-like success from every other lackluster thing they put out.
Samsung is just feeling the effects of everyone else having caught up somewhat.
Meanwhile- for my money, there's nothing that even comes close to the Note 4. The day anyone else has a phone that looks as good, has a wacom digitizer & pen, plus all the best features like removable battery, SD card, high res screen, etc then let's talk. Until then, IMO, nothing touches it. That it wasn't a huge departure from the previous Note3 isn't a big deal to me, since that phone was awesome in its own right.
Samsung seems more than willing to try new things that no one else has- the Note series in the first place, and now the Edge. Love it or hate it, no one else even tries nearly as bold designs.
Meanwhile, although it's not the most radical upgrade, people have to be just plain spoiled to pretend the S5 is any kind of terrible device. There's just more choice than there used to be (again, a good thing) so it's simply not the *only* thing anyone has to settle for- you know, like that *vaaaaaaast* choice of new phones running iOS!
I think Samsung just did exceptionally well when there was virtually no one else making Android devices to challenge them consistently in the past few years. Now that the competition has heated up and a few other companies have stepped up, their sales simply reflect the new reality. They're going to have to hustle more like everyone else (except of course Apple) and not rest on their laurels.
I'm glad for that. Companies resting on their laurels and celebrating huge successes for the same ol' same ol' is awesome for their bottom line and great for corporate cheerleaders rooting for one team or another- but it sucks for consumers.
Let Samsung sink or swim based on what they actually come out with and how people react to it- in a marketplace filled with competing products. The way it should be.
