Following the release of the Intel-powered iMac, MacBook Pro, and now Mac mini, Macworld UK is currently in San Francisco for Intel's Developers Forum.

The show couldn't be more dissimilar to Apple's own Worldwide Developers Conference. The keynotes lack both Apple CEO Steve Jobs' showmanship and the Mac-obsessed crowd to applaud his every move. In truth, the one moment applause was heard was when Intel VP Sean Maloney introduced the Apple iMac, which took centre stage for the keynote.

Another difference between IDF and WWDC is the fact that journalists are welcome to attend all the keynotes and any of the training sessions at IDF.

At Apple's WWDC, a handful of lucky journalists attend Apple CEO Steve Jobs' keynote but that is where admittance ends. All WWDC sessions are protected by a non-disclosure agreement and Apple rarely reveals details of any new products or technologies: in contrast, Intel traditionally does make revelations, but the feeling on the show floor this time is that Intel hasn't really announced very much at all.

Intel has offered an update on the development of its Conroe, Merom and Woodcrest chips - and impressive energy savings and performance increases. The company has also given a name to the underlying energy-efficient technology that will become Intel's blueprint for the future - Core Microarchitecture, described by Intel CTO Justin Rattner as "the culmination that both combines energy efficiency with the features and capability of what is expected in high-end machines."

The company has also unveiled plans to use flash memory to make it possible to start up a laptop almost instantaneously.

Apple has confirmed that it will hold its next WWDC in August 2006, the same month that Intel traditionally holds its Autumn IDF.
