Google has officially joined the ranks of Amazon, Apple and others in selling online music.

Apple iTunes and Amazon MP3 store, take notice. Google may be joining your ranks as a retailer of online music.

Tablet computers, such as the $199 Amazon Kindle Fire, may be all the rage now. But touch-sensitive e-book readers are getting a boost too, thanks to sinking prices.

On Friday, Apple issued a recall for its first-generation iPod nano. The iconic digital music player has built-in rechargeable batteries that may overheat and pose a "safety risk."

On Monday, Barnes & Noble is expected to make a slew of announcements regarding its line of Nook digital e-book readers—and possibly introduce a tablet computer, according to several tech websites.

Sales of Hewlett-Packard's tablet computer, the HP TouchPad, are expected to start up again, follow the recent fire sale of the HP TouchPads that were originally discontinued for poor performance and sales.

Motorola today announced the MotoActv: It's a rugged, fitness-focused smart music player that compiles the songs you listen to the most and determines which ones motivate you by monitoring your reaction, up to 4,000 songs. (And it looks an awful lot like an iPod nano.)

Apple today announced cuts to the pricing of its iPod touch and nano digital music players. The company also rolled out a white version of the iPod touch. The least expensive iPod touch will now sell for $199, while the iPod nano will go for $129.

Most of the speculation about Apple's October 4 press conference has focused on the next iPhone. But could it also mark the beginning of the end of Apple's other iconic device, the iPod digital music player?

Amazon will be holding a press conference in New York next Wednesday, and it's widely expected that the company will announce its long-rumored next-generation Kindles, and possibly even a full-fledged tablet computer.

Just in case you're looking for a more reliable source for information about the release date of Apple's next iPhone, former vice president Al Gore has weighed in. "Not to mention the new iPhones coming out next month. That was a plug," Gore said yesterday. He should know. In addition to having invented the Internet, he's a member of Apple's board.

You can now borrow e-books from public libraries on the Amazon Kindle, the company has announced. The move eliminates one of the Kindle's key competitive disadvantages, since the capability has been available for some time on other e-book readers, including the Barnes & Noble Nook Simple Touch and Sony Reader Daily Edition.

Do you have an Apple iPod that you haven't used in ages, thanks to your new iPhone? Or maybe you just need to ditch that two-year-old first-gen iPad? GameStop now says it'll take those tired old mobile Apple products for credit toward video games—or cash.

Amazon is trying to sell publishers on licensing their Kindle e-book titles on an all-you-can-read basis to members of Amazon Prime, the website’s premium service. The plan is no surprise: The notion of unlimited e-reading has great appeal, and Amazon already offers unlimited streaming video (albeit from a relatively small library) to Prime customers, who pay $79 a year for free two-day shipping and other perks.

E-book readers with full-color e-ink displays could be just around the corner, according to their proponents at a recent trade show. But this isn't the first time that color displays that use less energy than those on computers and today's color e-book readers have been promised—and then failed to appear.
