People say that carbon doesn't matter but I believe it does. Sure the speed should be about equivalent if coded correctly (even though usually it isn't) but the other thing I'm looking for is the cocoa capabilities like background scrolling. When Omniweb is below Adium, or vica verca, I can hit the command key and the scroll arrow and read through the forum without making it active. With the finder, I can't. Say I'm coding html and I need to know the exact name and path to a file on my computer. I have to either make my bbedit window really small or keep switching back and forth which sucks on 266 mhz.
