Sony said that by year's end it would switch to the EPUB set of standard formats for electronic books for its online library and Reader devices. EPUB-packaged books can still be wrapped in DRM, but are far more portable among devices and software than proprietary formats. Amazon's Kindle uses a proprietary book format for its titles, and does not read EPUB packages.

Google Caffeine is Google's new search engine architecture. It's designed to improve search speeds and results for users, but may also have some unexpected results for developers. PC World runs down answers to basic questions concerning the forthcoming changeover.

Some MacBook Pro owners with 500 GB 7200 RPM hard drives have been complaining of clicking sounds, followed by a short period of stalled performance. The machines become responsive again after roughly 10 seconds, and do not require rebooting. Luckily, Apple spokesperson Bill Evans has informed CNET that Apple is aware of the issue and working on a fix, though no definite timetable has been set for its release.

Nothing new here: Ars Technica reports on a new trojan horse, disguised as a QuickTime player update, that hijacks DNS requests, sending the victim to the attacker's Web site of choice. Common sense helps you avoid 99 percent of trojans and this case is no different - if an untrusted Web site instructs you to download and install some piece of software, don't do it.

This modestly amusing video from Slate about an iPhone developer who lost his iPhone picks up a bit at the end.

Developer Rainer Brockerhoff recently threw his two cents into the Apple Tablet wishing well, after which the Brazilian site Mac+ reprinted his musings along with gorgeous mockups from illustrator Mario Amaya. It's nothing more than a fantasy of course, but as Rainer told us in iChat, "One can dream."

Publishing on the Internet is easy - paper is hard. If you don't believe us, check out the amount of work that went into making a recent Macworld magazine cover showing the iPhone 3GS - it's a time-lapse video made by Peter Belanger.

Wonder what the real story is behind the famed Apple logo? Creativebits interviews Rob Janoff, the man who designed the now-iconic apple-with-a-bite logo back in 1977, and he sets the record straight about just what the apple is supposed to mean and why there's a bite taken out of it.

Ars Technica reports on Apple's recent decision to revoke developer Khalid Shaikh's iPhone developer license and remove his 900+ apps from the App Store. According to Apple, Shaikh's apps, which aggregated and repackaged news content, frequently drew objections from third parties for violating intellectual property rights. When considering Apple's claim of over 65,000 apps in the App Store, hearing news of such junk (another developer reportedly has 2,000 apps similar to Shaikh's) highlights the difficulty of finding good applications.

No, we don't know anything real about it - no one does. But it's our job as pundits to speculate when asked, so Adam and Your Mac Life host Shawn King bat thoughts about the much-rumored Apple Tablet back and forth in this podcast.

In his New York Times column, David Pogue offers a detailed comparison of Amazon's Kindle marketplace and Barnes & Noble's new multi-device ebook offerings. B&N suffers from too few titles, and a clutter of old public domain works from Google in search results. The initial Mac and iPhone versions require complicated navigation, as well.

The Loop covers Apple's small but appreciated gesture to iPhone developers: the capability to search for apps by keywords. With over 65,000 iPhone apps currently available, anything that makes it easier for apps to be found is welcome.

Macworld reports on Apple's rejection of both the Google Voice iPhone app and third party apps that interact with the telephony service. Apple cites the fact that the Google Voice app provides "duplicate features that come with the iPhone" as its basis for barring it from the App Store. Google Voice provides free SMS messaging and cheap international calling, thus arousing widespread suspicion that AT&T is behind the decision.

The Onion uncovers Apple's newest device, the iPhone 3GI, which boasts a wide-screen display that "features the most brilliant colors and finest resolution ever imagined." However, in a nod to the company's loyal fan base, only true believers can see the amazing device; it's invisible to everyone else.

Apple introduced AirPort Wi-Fi networking just about 10 years ago at Macworld Expo New York, and you can once again see Phil Schiller jumping from a platform onto an inflatable pad while holding the original iBook. Steve Jobs notes in the keynote that Apple worked over 18 months with Lucent to develop the system, which explains why AirPort performed better than any other 802.11b systems for years to follow.
