In short, this phone is running Android, an operating system a tad complicated for beginners but so well when you're used to it. Hardware side (components of the phone), I remain speechless in front of such value. Just for info, this phone, which was released a few months ago, is much more efficient than the new iPhone 6+ while it costs half the price.
The only drawback may be that the touch is too sensitive but this is minor.
Oh and last little thing, did you know that there is a small object called HTC Media Link HD which allows to broadcast live TV on your photos and videos from your smartphone? Even better, you can make powerpoint presentations with this! No need to bring your laptop computer huge for your next presentation, it is in your pocket !!!
