I really like the Thunderbolt, it's a fast elegant device, and is impressive in certain respects, but I have several gripes with it that may likely have me returning it and sticking with the Droid X till another device comes out.
The reasons I got it was because it was a true 4.3 inch screen over against the 4.2 inch more narrow screen of the Droid X (to allow texting/typing to be easier and faster), had "Dolby Surround Sound", which lead me to believe it had a better and or louder sound to it, and it's 4G which also lead me to believe it would have not just faster internet but also as good or better phone reception and quality. I was also hoping it had a better looking screen all around for video playback, even if it couldn't match or surpass the Droid X in regards to graphics. The fact that every day usage would be smooth even with many apps installed was another plus I hoped for. I didn't care that much about battery life as I always tend to get an extended battery anyways.
Some observations I've made that bug me and could be very likely be deal breakers for me, are the following.
The sound of the TB is not as loud or as good as the Droid Xs. This is a disappointing thing to have this be an issue in a device that says it has Dolby Surround Sound.. The Droid X has a Media Effects equalizer/presets that allows the bass to get much deeper, more dynamic, and warmer than the TBs. You can emulate that and or make music sound better or at least as good via an app like PowerAmp, but that doesn't apply to the entire system as the DXs does. With regard to visuals, I think that while the colors are more vibrant on the TB, it's my impression that the blacks are blacker on the DX, making it look sharper, and by contrast, the colors also look more natural and accurate on the Droid X than on the TB. The longer length of the DXs screen also helps to allow more of a wide screen feel to video viewing over the TB, that seems to be a bit more cramped looking by comparison.
I'm also getting poor phone signal, and no 4G in a 4G area. This is a really HUGE minus for me. Going from pretty good signal, 2-3 bars, excellent microphone/call quality, where I could be 7 feet away from the mic and people could still hear me clearly, to having zero to 1 bar, and NO 4G is absurd if this is supposed to be a phone UPGRADE. This may be due to tower provisioning, so I hope they can fix this. While typing on the TB is better, and really is rather a more enjoyable experience than on the DX, and HTC Sense is nice, still though because they load up so much bloatware I think it doesn't make the TB THAT much better than the Droid X in regards to the practicality of how the specs play out in real life. Using Launcher Pro and Beautiful Widgets makes the Droid X as good if not more customizable than the TB, even if it is more laggy after installing many apps on it, and having them run in the background. It will likely take a lot more for the TB to get laggy, though I noticed that the weather animations were a tad laggy from the get go, and the boot animation started to lag a bit after loading just a few apps.. so I don't know about this point just yet..
One thing that surprised me was that the weather animations looked better on the DX with Beautiful Widgets via Launcher Pro than on HTC Sense that they seem to want to emulate in some ways.
With these frustrations, if they can fix the coloration issue, the 4G provisioning, and sound issues, I think I may keep it.. but if not I think I will be returning it to wait for a possibly more impressive device like the Bionic, Droid X2, or something better..even though it is a nice device. 1080p video, HDMI out, and a dual core with 4G, though seem like a winning combo for me at this point. I realize it JUST came out, and they have issues they need to resolve being a new device.. but while I don't know if these things are a big deal for other people, they area big deal for me after shelling out 280+ dollars including tax, as well as the upgrade fee, not counting the Steinheil Oleo-phobic screen protector I already bought for it.. If I do return it within the 14 days, and wait for another device, if Verizon does tiered I may just jump ship all together after being with them for more than 10+ years.
