To be honest, i would LOVE to use Safari. I started using it, and it's just SOO quick to load up pages it's awsome.
The only downfall to safari is that some pages are not compatible with it. That's something that i DON'T like. So i use FireFox 99.98% of the time.
Example. myspace on Safari wouldn't load up my page with all the background i set up on it. So i though i was doing it wrong. Turns out, when i downloaded FireFox and saw myspace, that background came up and i was REALLY HAPPY, but sad that it was not viewable in my safari.
Then i went to
www.bmwusa.com to build my car. When i clicked on it, nothing would load up. Then i reloaded and reloaded and nothing. So i thought something was wrong with BMW web site. After a month same thing, so i tried it with Firefox and the pages loaded up fine and gave me access to build my car.
Also on the bmw site, to pay a bill, when i would click on the links nothing would happen, but in Firefox it would work fine.
SO, since most of the sites i go go don't always work on safari i still with FireFox. It's not a bad Web browser. I believe on the of the best out there. I would love to use safari because it appears more solid web browswer, BUT not all web pages are compatible so i have to use Firefox.
PS- I use firefox with isafari add on skin. Looks good!
