Besides, the title of this topic is "Are any of you disappointed with the GS4?" so it shouldn't come as a surprise that some users answer in the affirmative and give their reason(s). That makes them no less right (or wrong) than any other's personal opinion. In an open discussion, all viewpoints have equal validity.
Yeah, a new phone pulled out from a mysterious box to ultimately look like cross between the GS3 and Note 2. The build up suggested otherwise, that's all.
