Review: HTC One (E8) for Sprint
The HTC One (E8) is almost as good as the One (M8). It trades the latter's aluminum skin for polycarbonate, and in so doing loses a little bit of luster. Even so, the plastic is strong and well made. It still offers BoomSound and Zoes, but loses the TV remote and fancy two-camera setup.
The E8 has a great screen, offers good call quality, and includes killer battery life. I wish it performed better on Sprint's LTE network. The Android platform with Sense 6.0 is highly capable and highly configurable. Extras such as BlinkFeed and Wi-Fi calling help round out the software offering. It takes excellent pictures with the 13-megapixel camera.
I find it tough to recommend the HTC One (E8). It's a great phone, there's no doubt of that. However, there are a lot of other phones competing for the same price point - $99 on contract. For example, Sprint is selling the HTC One Harmon Kardon Edition, LG G3, and Samsung Galaxy S5 for $99 with no contract. All three have benefits the E8 doesn't (bigger screens, better cameras, etc).
In the end, I'd say the E8 is a bit of a niche phone. It's made for people who love the general design of the One line, but prefer plastic to metal.
