Can't wait for the review
I've been pretty disappointed with my Kobo Touch vs. the Kindles in the house. It's slow, the touchscreen is finicky about actually registering taps, it will randomly turn itself on in my bag and then skip 15 pages ahead, and the font selection is abhorrent. I don't gripe much considering it was half the price, however I do kind of wish I'd just bought the basic Kindle with buttons. But I have also heard that the newer ones are a lot closer to the Kindle in quality terms (looks like price also, unfortunately) , so I'm curious to see if they've reached rough parity.
I do hope you separate out the ecosystem from the other factors. For some, it certainly matters. For anyone who can be bothered to figure out Calibre, it's entirely irrelevant.
