I use the WiFI when I am loading something new onto the device, or playing with the social parts of the Kobo app., checking mail, surfing the web etc.

I can load apps over a wired USB connection by dropping the apps into the downloads folder and installing from there once I have unmounted the USB storage. I prefer to do most of that wirelessly, but you can make another choice.

PS: You can also add your non-kepub books in over the USB cable. And I bet you can even add in the kepub files if you copy them from their home on your computer to their home on your Vox. I never tried this.
