Chromecast for the UK

So, disappointed to realise that the Chromecast is not available in the UK today. I've been checking the Google Play Store, Currys, and teh interwebs in general, but no joy.
I don't know what I would do with it; I quite fancy signing up for Netflix, but I can access that through the PS3, so I don't need a Chromecast for that, The girls will probably end up using it for 'casting Youtube to the TV, and we can do without that.
I guess I just want to be at the forefront of technology; again, I think that tech will provide the answer, but really the Chromecast is a means to an end, and not an end in itself. Likewise my Chromebook, and my Nexus 7, and my HTC One X should all be means to an end and not an end in itself. But I believe the acquisition of new technology is driving us onwards, to consume more and more...
I've just replaced the battery in my One X for the princely sum of £45. I'm hoping that will enable me to put off replacing it for at least another six months. And then I am very interested in getting the Moto G as a replacement. £160 for a 16gb mid-range Android phone running the latest software with ease - nice.
My O2 contract is up for renewal on 5th April and I think I'm going to go SIM-only with Tesco. I believe they have a decent mix of minutes and data. I don't use many texts, so that's not important to me. With the combination of a Moto G and a SIM-only deal, I reckon I'll save a few pounds...
