Ti-maniac, I believe that people having significant difficuly with downloading/uploading are in the minority. I have used two different laptops without problems. The most that has happened to me is that when I started doing some programming this week, the firts time I connnected it locked up with the screen on and I had to reset. After that no problems whatsoever.
I suspect that those who are having significant problems have some problems with their computers - either hardware, operating system or both. Philips can't be expected to ensure their product works with every computer in the world (but it should ensure it works with most of them).
