Originally, "the device is bricked" meant that the device was about as useful as a brick, i.e. it had no useful functionality left couldn't be recovered at all. However, as the parent points out, it's been increasingly misused.
FYI, Korean have literally the same expression used in the web "벽돌이 되다", not sure if it comes from the english web though.
Anyway, the "bricked" expression is more commonly used in smartphones and PlayStation Portable (PSP) than laptops. Then it makes more sense when considering the size of the devices.

I think it's also at least in part more commonly applied to those types of devices because they're generally more locked down than a laptop, leading users to risk bricking by trying jailbreaking them. Installing a custom OS on most laptops just isn't nearly as risky in terms of bricking potential.
What everyone else said, but also, it's a particular kind of turned-into-a-brick: you can render something useless just by running a few hundred volts through it; "bricked" means that it's still functioning in some way, but because of a configuration problem it isn't listening to external input and never will again (because it also can't hear any input that might fix the configuration).
I started using this expression in 2006 when developing apps for flip-phones. It was common for the phones to fail to reliably receive app installation files and mid-way through the process, disconnect their serial ports from my development computer.
After that the phones would be, essentially, a brick.
I did not have the technology to fix it - a JTAG connector and software to drive a reinstallation of what I assumed was the firmware.
