Hmmmm. I think with the new wifi Nook available, the Kobo price will have to drop to at least $129 if not lower. The nook has several features not available to Kobo: touch screen, replaceable battery, built in dictionary, wifi access.
To be honest, if I'd known that B&N were going to release a $150 nook then I don't think I would have got the Kobo. Unfortunately it's too late to return it too, since i bought it about 16 days ago.
