next-generation Kindle(s) to hit the market? Growing increasingly frustrated with the wait? Thanks to the Amazon e-reader becoming Oprah Winfrey's "new favorite, favorite thing in the world (can't you see the jubilation on her face?)," you might just have to finally pull the trigger on the existing iteration. As a special offer for Oprah Show viewers (and by extension, everyone who reads this post), Amazon.com is now offering $50 off of the Kindle's $359 price tag by simply entering the code OPRAHWINFREY at checkout and envisioning Tom Cruise leaping on your computer desk. Better act fast, though -- the offer's only good through November 1st, and yes, that Tom Cruise bit is required.
