Amazon today unveiled a new addition to its Kindle line of e-reading devices, the Kindle DX. The most notable feature of the DX is its larger screen size — nearly 10″ on the diagonal versus the Kindle’s 6″ screen.

Amazon is touting the device as a comfortable reader for newspapers and text books, as well as e-books. Three major US newspapers — the New York Times, the Boston Globe and the Washington Post — have signed on to offer subscriptions at reduced prices.

The Kindle DX is priced at $489, $130 more than the Kindle. And yet, apart from the larger screen size, there’s not much more to love. It’s still a black-and-white display. There’s still no ePub or WiFi support.

Early reactions to the release of the DX has been lukewarm at best. Here’s at peek at some of the commentary from the publishing world circulating on Twitter this morning:

SmartBitches: Dear Amazon: please, keep it coming. I’m enjoying this way too much. I can has moar fail plz? Kthxbye!” #dud #amazonfail

paperhaus: Wondering why Amazon bothered with Kindle 2 at all. It’s not like they cooked up a 8.5×11 screen in 2 months.

ljndawson: $489 Kindle with 16 shades of grey and no discounts on subscriptions if you’re in the paper’s area = lead balloon. #dud

wmacphail: The Kindle needs to be WAY cheaper. Apple is going to kick this thing’s ass.

sarahw: Not getting over the $489 price tag. In a recession. Two months after Kindle 2 unveiled. Like reissuing bare-bones DVD w/ one or 2 extras.

kirkbiglione: No ePub, no WiFi. Kindle closed system continues and it won’t hurt Amazon one bit.

Only time will tell whether consumers agree and bypass the DX, or whether the large screen size will prove an enticement.
