HTC Desire Z hinge. is there a problem ?

dont buy desire Z ...it has a serious hinge problem...my friend who is always in to chatting wanted a qwerty keyboard phone and bought desire Z...and after about 2 months it got a bit loose and he was very uncomfortable with it...and the screen is also of very low quality, the camera is also not good either and the sound sucks...only thing i liked about it was sense and metal body...then he sold it at ebay and bought the Nokia E7...the hinge is much more stronger than desire and it has a very good display actually the best one i have seen and it has a very good 8mp camera and its got aluminium body which is superior to desire Z...and it got a bigger screen than desire Z...so in my opinion dont buy desire Z...buy the E7 instead
