...is my PSP.
If there was a fire, that would be the first thing I'd grab. It's been almost 4 years since I've had it and I'm still in love with it.
My dad went to Japan and he asked me if I wanted anything. I jokingly told him to get me a PSP. I didn't even know what it was...
I know many people who just have to have their cell phone, or laptop to survive. For me it is my PSP. It has helped me pass so many boring hours during travel, or just waiting for something to happen, that I don't know what I would've done without it.
