Down from $649 (which is an obscene RRP), the series 9 now seems more reasonably attainable. There is a chrome version for $399, but I can't tell whether there is any difference other than the colour. I'm happy to miss on the chrome and save $50. Don't forget shopback (7%), which would bring this down to $324.55!).
There are other deals as part of click frenzy.
