This is my 2nd 2011 13" Macbook Pro. I exchanged my 1st one for another because my screen came with water marks and because of this "click" I hear coming from the bottom-right corner (where your right wrist is when you're typing). I hear this "click" more often right after I turn it on from sleep, after I lift up the screen, move or slightly bump the bottom-right-corner, and pick it up off of my desk to take to the living room. It's pretty loud but you probably can't hear it if you have music on. Also, even after restarting a couple times, Safari is still freezing up and I'm getting the "you are not connected to the internet" when I click a link from a site it just took me to. How am I NOT connected to the internet when my other tab is browsing fine? For example, I google something, search results, great... click one of the results and then "you are not connected to the internet." Although this processor is much faster and I love it, there are little annoying stalls and delays that remind me of my Dell Desktop PC. The 2010 model and previous models, I felt differently when I used. It was "boom, boom, boom!'' Nice and crisp. This processor is a bit louder, which I don't care about, but it's sort of a quicker boom, boom, wait a second, boom! Keep in mind, this "wait a second" only happens once in a while. The thing is that I don't have ANYTHING installed or ANY of my files transferred over yet and am only using the Safari browser. Hope it doesn't get worse when I get all my stuff on here. If you have a 13" 2011 MBP please: After turning it on from sleep, lift your MacBook up from the right side and listen for a click. And also, put it on your lap with it on and running Safari. Then push the bottom-right corner down continuously so it's like a see-saw on your legs. Do you hear a click? I will ask Apple about all this but I will be keeping this beautiful machine. keep in mind I DID purchase Applecare.
