Connecting your device may be an adventure.
You may need to go to the device manufacturer and download a driver.
Then on the device itself you need to go into the Developer Options and turn on USB debugging.
Now if that starts to become a hassle and you want to get going....
I use DropBox on my desktop and phone.
I build the APK to dropbox .. go over to my phone open dropbox and install it.
Very easy and on a high speed connections it doesn't take very long at all
(You may want to connect to a wi-fi if your on a limited data plan)
Drop box is completely free and a good place to stash some files you want to access on multiple computers or perhaps share with other people.
*you files are not shared by default so don't worry about that
