"Verizon's first LTE phone was worth the wait"4.5 starson by karmamule
Pros: Large, bright colorful screen, Sense 2 UI is fantastic, LTE speeds are blazing fast, phone itself is very fast, solid construction, good sound, excellent call quality
Cons: A large phone that people with smaller hands may not find comfortable, eats battery power like candy, only those in areas w/LTE will see full benefits of the phone
Summary: The HTC Thunderbolt is a bold,large phone that is solidly constructed and people who like big phones will definitely like the form factor. Those who want small, thin, svelte phones may want to look elsewhere.
The rubberized back makes it comfortable to hold, and the bright colorful screen is impressive. It appears faded when viewed at an angle when compared to an AMOLED screen, but is gorgeous when viewed directly.
Call quality is superb: I haven't had a phone with call quality this good in *years*. People sound crisp and clear to me, and they say my voice sounds very clear as well.
LTE speeds are blazing fast (I've seen as high as 18mbps down). They'll no doubt slow down as more people get LTE phones, but it should still stay significantly faster than any other non-LTE "4G" networks.
You also get simultaneous voice and data whether connected via 3G or LTE, so that's a pleasant change for Verizon customers.
The phone comes with a generous 40Gb of memory split between 8Gb internal and a 32Gb microsd card. (However about 5.5gb of that internal memory is already spoken for when you first get your phone.)
Despite being single-core, the Thunderbolt's performance is impressive, and always feels crisply responsive.
From reading the forums it seems a few people are having problems that ultimately seem due to bad sim cards, but my experience has been wonderful: the phone seamlessly and quickly switches between wireless, 3G, and 4G as signals become available, and Sense 2 improves on an already excellent Android-based UI.
Is it worth pulling the trigger and getting a Thunderbolt or waiting for the Motorola Bionic? I'm a big fan of HTC & Sense, so for me the question was an easy answer. If you have an Incredible and really like it, I'd say you should go for the Thunderbolt. If HTC and Sense aren't as important to you, but you live in an area that already has LTE you may want to start taking advantage of that too, it's like night and day!
If you don't have a preference for HTC/Sense, and don't live in an area with LTE yet, then I'd say wait a little longer, but otherwise the HTC Thunderbolt is a very fast phone that is great at meeting the most data-hungry of users' needs.
