I received the Kogan in the mail today...
It looks like a solid unit... I really like that it supports so many formats as well as the ability to change margins, line spacing etc. - and it support folders. It has folders already for music, photos, books etc
I was surprised to find a USB Wall charger, but it did say so in the description, but I must have missed it.
The screen is beautiful and clear.
It has 1500 pre-loaded books, and the books I've looked at all has got something to do with Australia.. They are of course public domain (Gutenberg Australia), but well formatted and I haven't found any errors in them, yet. To see how the reader performed, I started reading My Experiences in Australia by A Lady (Mrs Allan Macperson) - So far I'll continue reading this book.
The page turn button is a bit hard to press (maybe it'll soften over time?)... And then there's the book marking.. Two clicks 'menu, book mark'
These are the only 2 things I don't like about this reader, but other than that, I think it's great value for money.
I did have a Kobo reader, but I didn't like it much... The Kogan is a lot more user friendly due to the large amount of personal preferences settings.
