They're in manufacture. Rumour has it they may be ready around the end of next week.
I've been driving around with one in the car today (it's actually rather sunny for a change) - seems to do the job, although if you're expecting miracles you'll be dissapointed. With a blue screen I haven't yet been unable to read the screen in direct sunlight, although it does wash out somewhat.
The display looks a little blurry compared with the uncoated screen, but that was also the case with the Mk.1 - if you haven't seen anything different you wouldn't notice. In fact, we could market this effect as hardware anti-aliasing
