I've got a bunch of utilities (some in beta) that are sometimes "a solution waiting for a problem":
- adbsync I use daily to sync my desktop with devices. Content goes from desktop to device, notes and photos go back
- adbgrab allow mirroring of the screen and taps, typing, but slow as it does not use any utility on the device itself
- keyer a hardware solution to allow very fast automated typing from desktop to device
- swiper a software solution to turn a master device into a controller for a slave device, useful for broken screens
- copyclip an Android utility for inserting text into the Android clipboard
- adbclip a Windows utility for copying the Windows clipboard to copyclip
