I switched from Chrome to Safari 5 months ago. The memory usage in Safari is far more superior than Chrome / Firefox on OS X. Also the CPU usage is relatively low, which means more time on battery for me. I still use Chrome for development, though. Safari, is not as bad as IE6 was and anyway no professional front-end developer would make a website that is not working properly on iOS Safari, so it's kinda obvious it will stay supported for a long, long time. So I would consider what the OP is doing with the CSS, something that might also work on Safari, but with some polyfills.
