I purchased an Ipaq 6915 in september. As soon as I learned that its screen is glass. I attached all the armours it has and kept using them all the time (i.e. tinted plastic faceplate and beltclip).However it fell off from a coffe table the other day(only 35cm height!) Its glass screen has a crack on the corner. Otherwise its functions work properly, only I am unable to calibrate its stylus. I took it to repair centre here in Istanbul. They consider it as an absolute "customer fault" and firm on that, so they faxed me a bill of 269USD plus VAT. One third of its price! There is certainly no scratch or anything on the body, since it had been taken care of very well and only fell from 35cm. One wonders if HP has a policy of making money by changing higly fragile and expensive spare parts.
intending to buy an Ipaq (6515) think twice again!
