For years, I have been using Safari only. I tried Firefox on a Mac, Opera, SeaMonkey and Chrome, but I just loved that Safari supported multitouch gestures.
Then, a week ago I saw a thread about Safari. I joined and I saw some hardcore Mac fans slagging off Safari and wondering whether anybody used Safari at all.
I felt sad and for a whole day I used Firefox (now it supports three fingers) and Chrome. Actually, they were faster than Safari. But that's about it. Since I upgraded for 4GB RAM and I have a 7200rpm HDD, I hardly see any beach ball, which was a regular on my 13" MBP.
Things look just nicer on Safari. I'm not a web editor and I don't need Firefox's plug-ins anymore. So with this speed update, what's the point of using anything else than Safari (apart from annoying Jobs)?
If it's the multi-touch gestures that have been holding you back, there's a program you can use to create your own gestures. It's in beta, but but I've been using the non-alpha builds since November with no issues.
