It's been causing us a few moments of chin scratching, trying to work out why iMovie will work on the new iPhone G4 but not the recently-released and already stupidly- popular iPad.
But it looks like the foks at Mac Rumours (opens in new tab) have unearthed a snippet of information which explains the disparity. The iPhone 4 will have 512MB of RAM, twice as much as the 3Gs or indeed the iPad, according to the Mac news portal.
The information has also been confirmed by a video of a session from last week's WWDC which has been published by Apple, but is only available to registered Apple developers.
All three iDevices will eventually run Apple's forthcoming iOS4, and both the iPad and the iPhone 4 will be powered by the Cupertino company's home-brewed, Arm-based A4 SoC, but it looks like iMovie will need the additional RAM to run.
The additional RAM will also boost overall performance and allow the latest iteration of the Holy Handset to multitask, a function which has been notably lacking in all previous versions.
