I have just learned that Best Buy is now carrying the Aura, Aura HD, and all 3 of the Android tablets that Kobo launched this Fall. They only have the black models in stock, but even so that's a major improvement on 2 weeks ago when BB didn't have any of the new hardware in stock.
Best Buy's stock situation is also significantly better than that of major chains like Target, Walmart, or Staples or even indies like Powell's or Family Christian BookStores; none of those chains have the new Kobo hardware listed on their website. It's not just out of stock; there's no mention at all, nor do they have the hardware in store (I checked).
So is the hardware worth it? Yes and no.
Aside from a new shell, the 6" Kobo Aura is an improved and updated version of the 2012 Kobo Glo (much like the 2013 Kindle Paperwhite is an updated version of the 2012 Paperwhite), but the Aura HD is a horse of a different color. That is still the only ereader on the market with a 6.8" screen which has a screen resolution that no other ereader can match.
And as for the tablets, when they were announced in August I compared their specs to other tablets on the market and found Kobo's 7" tablets wanting (the jury is still out on the 10" Kobo Arc 10HD). In the 4 months since that post I have reviewed a dozen tablets, many of which had decent performance and price tags starting at under $100, and I don't see a reason to change my mind.
I still don't think Kobo's hardware is worth the price they put on it, but don't take that as a firm recommendation until I get a chance to review them. The Arc 7 and the Arc 7HD are the next 2 items on my todo list, and I plan to have review up by the end of the month.
