Don't pay attention to the blog reviews. Ignore them. Go for the reviews of the Kobo Glo and the Kindle PW from actual users here on MR. Those are a lot more realist and are from actual owners and not someone getting paid to do a glowing review or missing things because they don't always do proper reviews.
When was the last time you've read a review on a blog that actually mentioned how good the software on the device is with real use? Not often. They leave important things like this out of their reviews. Also, I bet they get hand picked units sent to them so when they review it, it will be a good review.
