As an owner of one unit myself I can truly say that the "iPaq 6515" is NOT all that good. Having a ton of useful features, it lacks the most important - Quality. Cingular (the official provider) will give you a hell of time if something goes wrong or breaks and all you want is just to exchange it. They will ONLY send a refurbished phone, even if a brand new one was purchased. 3/4 of Cingular Customer Service don't know what GPS is and will give you a forever runaround. I was VERY happy with this phone, up untill all sorts of hardware problems start accuring.HP support are hard to get a hold of and most of them know less the the consumer.The reason for this AMAZON reveiw is hopes that many people will see it and think twice before investing so much money!Thank you all.
