I'm still waiting for mine to arrive via the SonyStyle store (hopefully Tues the 29th). Sony didn't send out review units to review sites as far as I know
. Hence I had to buy one but since I personally enjoy my PRS-600, I won't cry in my beer. At any rate, expect a review on MobileTechReview with video review this week.
I'll be looking in screen quality vs. the 600 and 505, store experience on device, handling of ePUB and LRF and periodicals. If there's anything else you'd like to see covered, please post.
