Apple released a Windows version of Safari (their web browser on the Mac) a while ago. I downloaded it and gave it a go, despite the many reports of it being terribly buggy.
Well, for me, it seems more reliable than Firefox – I only managed to crash it once in a couple of days of use, where Firefox crashes several times a day under my use. The down side is how it handles crashing. Firefox brings back all of my windows and tabs, maybe losing the last couple I’d opened. Safari just opened up again from scratch with everything gone. Not graceful.
Still, it doesn’t seem bad for a beta release – I’m looking forward to seeing how it goes – worth trying out if you’re interested, just don’t rely too heavily on it yet.
