There is a lot of noise surrounding the HTC One X. So I keep an eye on the reviews.
I am a huge fan of HTC but the fact that the battery compartment is sealed and the SD card cannot be removed are, for me, a deal breaker.
I have enjoyed the option of being able to upgrade my SD card or carrying a second battery I can slip it into my phone in a matter of seconds. Since I read the battery life is not great, it may be a huge problem for some who are not always close to a power source… I hope HTC revert their decision on these points…
Anyway, a review on the HTC One X, from CNET UK you may be interested in.
