I bought a Sony PRS300 last night -- after literally months of agonizing about which way I'd jump to put a bookcase in my purse.
Set up was easy thanks to some great posts in this forum covering the things that the Sony manual does NOT tell you. Like that weird "don't disconnect USB screen."
I'm sure I'll be back with questions, but right now I'm enjoying reading my checked-out books from the Seattle Public Library thanks to your wonderful information!!
