Hi Al,

You've probably already done this but check your site stats to get an idea of who is using what and, as Tim says, if you don't officially support earlier version you probably have leeway there. It will be interesting to see what percentage are on desktop and mobile

Also keep in mind that due to the nature of the site many users might not have the new shiny things. Having said that in user testing we've generally found that people who are unemployed or retired tend to not have desktops or laptops in favour of tablets and mobiles (Disclaimer: this is very anecdotal).

One final thing, do you have any apps for iPhone or Android? This might be an alternative for some but obviously can't be used as an excuse not to implement something on the web side correctly.

Changing the fallback from px to em will involve a considerable amount of development time to fix due to the font size compounding issues with em - and will also result in a messy and harder to maintain codebase. Is using rem with a px fallback an acceptable/accessible implementation?
