It is very easy. I got it for my birthday 3 hours ago, and already have it all set up and working fine. I did the wifi setup, synced it to my Kobo account, and can access all of my books on it. I tested it with a micro sd card, and can read the non drm epubs and pdfs on it. I have authorized it to my adobe account, and can put library books on it. And finally, I can access my Dropbox account and download books from it. It turns on and off fine, sleep mode works great, and the glow feature is awesome! I also tested the extras, they seem fun but I don't know how much I'll use them. I recommend this to everyone, it is a great little reader. Now my family gets to fight over who gets my old Aluratek.
If anyone would like, I can do a more detailed explanation of any or all of the process.
