Ignoring the font hinting (the font is barely readable when fully zoomed out - in contrast to on iOS and Android, although with the 4S and HTC One I had retina screens, so maybe it's not a fair comparison), the only thing really annoying me with the browser is more a general Windows Phone issue - in text boxes, I haven't worked out how to move the text caret position in the URL - by default it seems to autoselect parts, meaning it's very tedious try to fix incorrectly-typed URLs... I guess the answer is get it right first time...

I wish there was a way to make "Open in new link" tabs open in the background like on Android as well, but as far as I remember iOS had that annoyance too.
