The TIME review is pretty strongly worded:
They look at the Nook Glow (after its trimmed price) and compare it to the KPW:
The bottom line is that the Kindle Paperwhite and the Nook Simple Touch with GlowLight are both well-done gadgets. Each one has some advantages over the other; neither has any crippling flaws.
But that doesn’t mean that these two e-readers are evenly matched. Amazon decisively wins this round, thanks to its remarkable new screen. Unless you’ve already invested copious amounts of money in e-books from Barnes & Noble or another company — most of them aren’t easy to move onto Amazon’s hardware — the Kindle Paperwhite is the e-reader to buy. It’s the best one that Amazon, or anyone, has built to date. It’s also the best product that Amazon has sold under the Kindle moniker — a refreshing reminder that there’s always room for a device that does one thing really, really well.
Bold highlight mine.
A nice reminder to the multifunction device fans.
