What hardware do you use?

I'm using a 2010 MacBook Pro, with big dents where I dropped it twice. The screen's once-round corner is now polygonal, and the case near the hard drive is now crumpled. The second impact disturbed the connections between the body and the screen, and produced weird teal stripes over everything. I tweaked the color balance until the stripes went away, and now the display looks normal except for everything that used to be black is now pulsating a deep demonic red. The battery life is approximately one hour, and maybe 15 minutes if I'm running a neural network. It's got a GPU, but it's too old to run CUDA, forcing me to do CPU-based computations instead. So I'm thinking of maybe getting a new laptop one of these years.
