I did everything wirelessly. Today was the first time I plugged it in, and it was to get the update. But I was able to authorize it at the sony store on WIFI. As I said somehow I got some weird eroor message about adobe ID. But I just went back to the home page and when I tried again I was logged in and everthing was fine after that.
So far I was able to download books from the local public library, and the natioanl library of singapore. And papers from dropbox. I doubt I will plug in this device too often.
