Chromebook 13 keyboard keys resonate + trackpad?

Hello all,

I'm having a bit of trouble with the search feature but so far haven't found any info. I figure to post while I keep looking.

So, I just received my CB 13 and it's a beautiful machine. But when I play audio, at or above 50%, the keys resonate noticeably. The higher the volume goes, the worse it gets. To me, that's totally unacceptable. I used a tone generator to help me pinpoint it and it appears to come from the keys. If I put my hands over the keyboard, it goes away completely. Remove my hand, and it resonates a lot again.

Has anyone experienced this issue with the CB 13? 

Also, the trackpad seems a little finicky. I had trouble click and dragging - it would go all over the place.

How does Dell handle exchanges btw? I hope this isn't a common issue across all CB 13s :(
