Firstly, it is great to have found this forum.
I bought the hx4700 in Australia over a month ago and took it traveling. My partner and I used it to document our trip and we managed to type, using the stylus and onboard keyboard, a document over 150kb.
The result of this is that we have a great journal but the screen is permanently marked with dots especially on the vowels and other functions that we used allot. The stylus seemed smooth at its tip but obviously its not.
On return to Oz I asked a few shops that sell the 4700 if they have heard of this problem before. None of them had?
I could not believe that a screen built for touching and tapping on would only last for 150kb. So, I called Hp Australia to see if they could replace my screen and stylus under the warranty. They do, and I wait the return of my 4700. Lets see???
Has any body had this problem? I have read in these forums that a screen protector is the way to go. If so, what brand in Australia would be recommended?
