But it is true that the mobile versions of a lot of sites are only tested in Webkit because Apple and Google are so dominant in phones, so if Canonical is making a phone OS then they probably want to use a Webkit browser. And if their phone OS uses Webkit then their desktop OS does too because they're the same. So now that I think about it, yes of course they should switch to Chromium (even though I would say Firefox is much, much better), and they'd better hurry up about it, or they'll have a bunch of users complaining that Ubuntu "doesn't load websites right".
No announcement yet.
Ubuntu Will Stick With Firefox Over Chromium For Now
