i did not have the desire, but I hope that you find this helpful.
Despite all the "benchmarks mean nothing" comments the Sensation is last in almost every review you will watch on youtube or on the major internet review sites. it is NOT by accident that Galaxy 2 owners are in love with the speed and it gets great reviews for being over 3000 when quadrant. The same holds true with the LG GX2. It has problems, but everyone raves about the speed. That IS NOT the case with the Sensation. One one had people say that they love the phone and that it is fast "enough" but in the next sentence they can't wait for the root so that it can be opened up and reach its potential...? Hmmm..I like the phone a lot. I am not enamored with it.
If you want great standby time, a great camera, good movie playback, a sturdy feeling build and very good download speed then by all means get the Sensation. It is a good phone. Conversely, if you are looking for a game-changer phone or a phone that makes you say: "Hey, you gotta get this phone because..." this, in "MY" opinion, is not that phone. Why? Despite what you may read, there is a lag or an average feel to the speed of the processes. Just on physical comparison alone, I took my Sensation into a Sprint store. I played with the Sense UI on both phones. i CLEARLY saw a difference is speed and sensitivity in the EVO 3D compared to the Sensation. I also saw a delay in the way the app screens popped up when I wanted to add widgets to the home screens. I could see it in the flesh. Also, the speaker is horrid. Absolutely abysmal in playing music and movies. There are volume apps you can buy, but for a multimedia phone I am severely disappointed in HTC's effort. The front facing camera is too dark and looks like it was one of the last features htc worked on before they boxed up the product. Then there is no kickstand to prop up the phone so you can take advantage of the multimedia capabilities of the phone. smh.
There are more things, outside the specs and other observations I made that don't involve the build of the phone. Exterior annoyances like defective cases, screen protectors (sold at the t-mobile store) that don't stick because of the curvature of the glass screen and a paltry offering of accessories, but your experience my be totally different than mine. I have read some people have zero problems and then there are some that are on their 3rd phone. It is really up to you during your trial window to put it through its paces. I kept mine knowing the good and the bad. Decisions my friend...
