For those considering a Kobo, I haven't played with the new glow, but I've played with the previous two models. They're okay, I suppose, but they are slow and clunky compared to Sony models. I wouldn't touch a Kobo with a barge-pole.
I also don't want a Kindle. No buttons and selling my reading soul to Amazon is a big

I like my platforms open.
At this rate, I might have to start looking at smaller producers like Cybook in the future (the Opus was neat). Mind you, I have several backups ereaders I got from ebay

So no hurry. Light and hi-res screen would be nice though
