Thanks so much, I just just just ordered a purple one based on all of these excellent reviews, and robertb's chiming in on lots of them helped too.
My dad bought me a sony 700 back in July, and I returned it due to it not being mac compatible, and reading reviews saying mac compatible ones were going to be coming out, and cheaper ($549CAD for the 700? That's a whole lotta new shoes

)
Just went a couple days ago to check out the 300 and 600, and did NOT like them. I've been reading on my itouch the last month, and prefer a smaller font/less page turns- the 300's smallest font size provided the same wordcount I get on my itouch, so what was the point really?
I'm so excited, hope it lives up to my expectations! So once again, thanks.
One question though, says 3-8 font sizes...How does one get the smallest font? Does it have to be a certain format ebook?
