Puter.
I tell all the new guys i see to start digital early, It makes it much easier to read/present and you can back it up. I use logbook pro and it takes a little figuring out/educating the Kinko's guy if you need to print it but its pretty user friendly. Aside from that filling out any time related paperwork takes 5 minutes. I also dont pay for the cloud, i just email a copy of the file to my email every time i update. (free!)
