Just made the switch from PC to Mac today. Few questions about my glorious new macbook pro: 1. Is it normal for the upper half of the trackpad to be harder to click than the lower half? I have to put a lot of pressure on my finger to click the upper half but the lower half clicks with greater ease (i use tap clicking so it doesn't really matter, but I'm just curious). 2. I messed with the brightness settings, but was too indecisive so I just put on auto brightness. So will the brightness change, say, whenever I walk into a new room? 3. Is there any noticeable improvement in using the 9600 videocard? Everything is running great and I'm not playing videogames, so would turning on the 9600 make any noticeable difference? If so is it worth the battery life? 4. I used to use firefox, so I was spoiled by add ons like linkification. Does safari have add ons? Does safari run better than firefox on macbooks at all (since apple makes it, I dunno)? 5. I'd like to keep my laptop on all night since I'm transferring files to it. Is this safe (it would be plugged in and would be closed)? 6. What's a good website for getting delicious 1900x1200 pictures for this beautiful screen? Yeah other than that I seem to have this computer down. Love it, too.
