To be fair, reviewers do the same with any extra large phone (which is what the 6+ is). I'm not sure if I agree with it or not, but at least they're consistent![]()
Yeah, most tech reviewers seem to have issues with all phablets. The 6+ is great for those who don't have tablets and/or rarely use an iPhone as a phone. The 6 is probably better for those who plan to predominantly use it as a phone, have small hands, or already have a tablet they use. There's no doubt the 6+ is a slightly better piece of equipment with its camera and batteries, but that doesn't really matter if its not ideal for use as a phone.
Form factor is an important aspect of reviewing tech products. In fact, I feel like I remember when the MacBook Air finally became good enough to use as a main computer tech bloggers/reviewers all basically said unless you really want that bigger screen or do serious graphics stuff, the MacBook Air is the computer you should get.
Also, after so many years of tech reviewing (especially in phones) being about how smaller is better, its probably hard to switch gears.
