This doesn't quite replicate the pull to refresh on phones but I think the right implementation wouldn't conflict with the expected behavior on desktops.

All it takes to refresh here is to scroll past the top (however barely) whereas on a phone you have to give it a little tug to make it refresh and if you don't pass the threshold on the tug it just bounces back, effectively taking you to the top of the page. I think this is really cool idea and a good implementation but the next iteration would benefit by requiring slightly more 'pull' to activate than you would use normally when doing a simple flick on your trackpad (or scroll on your mouse) to get to the top.
