Everyone likes portable electronics and computers which is why cell phones are so popular. But so are tablets and notebooks which can give you full processing power but without the cord.
Manufacturers keep pushing miniaturization and the latest is the Sirius B from Ockel. Smaller than many cell phones, the Sirius B is a full-fledged Windows 10 computer complete with HDMI video output, USB, wireless, Bluetooth, 2GB of RAM, 32GB of flash storage, an SD card slot, and a quad-core Intel CPU.
And at $189, it might just replace your desktop PC.
