Annoying Trackpad Issue

Hey guys, I have a slight problem with my trackpad. It sometimes doesnt respond to taps or clicks, and the double tap right click is delayed for about 5 seconds, especially annoying when I play fps. I still have the one year warranty that comes with every mac, and I have the extended applecare warranty. I don't know what caused this to happen, just started after I had a software update.

So, am I eligible for a replacement trackpad, or even better, a replacement macbook?

 

Wow, that was a fast reply. Sweet I'd really like a new trackpad. I wouldn't mind waiting for a day or two. But in my country, it'll probably take a week or so *sigh*
