Ok so I am letting steam off. I just spent hours on the stupid Sony Reader PRS-505 that I bought against my better judgment from London. Unless you are a tech specialist, and not any tech specialist, working for Sony.. don't bother with it!
First of all you have to install the Sony Reader software that restricts you to buying ebooks from Waterstone UK, if you manage to do that, with limited book selection. Then you are required to install another software -some adobe software- that can read the ebooks. Then you have to transfer the ebooks from one place to another and another.. Needless to say I never managed to do that. And there were lots of plug ins you need to find and install.
I never had such issues with the older version of Sony that I bought online from the US. This is not user friendly at all and is full of complications.
