Amazon could hardly contain its excitement over how many Kindle devices it sold on Black Friday and Cyber Monday, the busiest offline and online (respectively) shopping days of the year. According to Amazon, the holiday weekend was the "best ever" for the Kindle family, especially Cyber Monday, which ranked as the biggest day ever for Kindle sales worldwide. It was pretty much the same situation last year, which makes it even more impressive that Amazon managed to double its holiday weekend sales record from 2011.

You'll notice we didn't include any clothes items in our Geek Holiday Gift Guide 2012 or Black Friday 2012 and Cyber Monday Ads Round Up. It's because we're far more interested in dressing up our desktops than our waistlines (this isn't Maximum Fashion, after all), but had we included clothes, would you know which size to buy, especially after eating a pound or two of Thanksgiving turkey? (Happy Turkey Day to those of you who celebrate, and to the rest, Happy Thursday, as it were.) A new virtual tape technology might one day help you figure it out.

Auction site eBay is rolling in riches as its online business continues to boom. Revenue for the second quarter ended June 30, 2012 spiked 23 percent year-over-year to $3.4 billion, eBay said. Second quarter income on a non-GAAP basis reached $730 million, up 16 percent compared to one year ago, while GAAP income hit $692 million. PayPal is a big reason why eBay is doing so well these days.

Zappos, the online apparel shop acquired by Amazon in July 2009 for $928 million in stock and cash, began alerting millions of customers over the weekend that it was hit hard by a data breach that may have granted cyber crooks access to sensitive account information, including the last four digits of any credit cards on file. The database that stores full credit card information and other payment data was not affected or accessed, the company said.
