I'm on 20Mb/s as part of the 'triple XL' deal, which means the enhanced speed is discounted as part of the bundle.
The main advantage to me is that when I want to download a file e.g. a tv programme in x264 720p format , which is about 1.2MB, I can get it in less than 10 minutes.
- as that programme then takes around 40 minutes to watch I don't see any advantage in downloading it any more quickly. As such, the ratio of download speed to viewing time is about right for me - there will be a case for 10Mb/s, also.
- I personally cannot justify a 50Mb/s connection for the way I use the service, but other opinions are available
