Anyone else have horrible lag/choppiness when scrolling and zooming in safari/preview/etc? Mavericks is better but it's still horrible compared to my 2012 MBP. The more complex the content the worse it gets. The HD5000 drivers seem way underdone. I get corruption over the bookmark bar in safari sometimes too. On a side note my trackpad makes annoying noises sometimes too though at this stage it isn't impacting it's functionality. And my last two iPhones have needed the home button replaced. Apple needs to remind themselves of why many people have grown to love the company; because their products "just work". Sadly this isn't the case for me lately.
