Despite the Windows Phone Ads appearing in the UK in 2012. I didn't really find out about the platform until October 2013 when I was looking on the internet for a new phone. I was surprised when I found out there was a windows mobile released over a decade ago and there were windows phone 7 phones available since 2010! I really thought the only phones were androids and iPhones. Look at me now on a forum for windows phone.
Basically, post here when you found out about this windows platform and how you found out about it. I'm sure I'm not the only one who didn't know there were windows phones in 2010.
I basically had a similar situation to you mate. In March 2013 I was ready to get a new phone -- I had the Nokia 5800 Xpress Music, which had lasted me 4 years and was still going strong. However, the stylus kept on falling out of the phone, so it started to get frustrating, hence the change.
Due to me being on O2, I decided to look for another Nokia phone on their website. Surprisingly, that is when I first found out about WP8 -- up until then I had no clue that it existed, let alone WP7. Funnily enough, this is a prime example of Microsoft's poor advertisement campaigns.
Nevertheless, I decided to give it a go, because of Nokia and the fact the OS looked different. At the time, the whole of my household were on Android phones -- mainly Samsung and HTC, with another 5+ Blackberry (Wackberry) phones in the cupboard collecting dust. This was due to Blackberry phones being broken, because of being manufactured from cheap materials -- although they cost as much as my Nokia.
Anyways, I played around with my L920 for hours and was fascinated with the Tile concept, plus the sheer beauty of the photo hub, amongst other things. Therefore, I persuaded my Mrs and kids into getting WP8 because it seemed a winning combination -- Nokia for hardware and Microsoft for software. Even if the kids had said no, they would have got them regardless, as we were paying for them. So we ended up with five Nokia phones in our house.
Having said that, two of my kids went back to Android (Sony) because at the time WP8 was inadequate for their needs. And the other changed their L820 for L720 because it was lighter and better looking. At present, we have L920, L820 and L720, which we are happy with because the phones and OS are beautiful compared to Android.
