I had some Microsoft's own web pages I had to print (on Vista Business). Neither Internet Explorer 7 nor Firefox (2) could print it. I then tried with Safari, and it printed the pages fine. So yes, you have understood right, Safari does work on Windows

My current phone (Sony-Ericsson P990i) is starting to show its age, so I am thinking on buying new phone. On my current phone I have some extra programs I use all the time, so I like to know if there are similar features (either coming with the phone or as extra software) on iPhone: -...
