One anonymous report reveals what could be the technical specs of the next generation iBook line. Although the source's reliability cannot be verified, the information coincides with older reports and appears realistic enough to be considered.

According to the recent report, Apple is going to speed-bump the iBooks with PowerPC G4 processors running at 1.33Ghz in the entry level and 1.42Ghz in the mid and high-end. No change on the form factor was mentioned though.

As for the graphics, Apple should significally boost them with a Mobility Radeon 9600. Current iBooks use the Mobility Radeon 9200 with 32MB of VRAM. We can note that a Radeon 9600 would meet the official requirements for Quartz 2D Extreme to be enabled on Apple's bottom line laptops.

Storage and RAM are expected to be increased as well: a 40GB hard disk for the entry level and a still 60GB for the mid and high-end models. Standard RAM should be increased to 512MB across the line but older reports suggested that the entry level iBook would remain with 256MB.

The source believes the new iBook line will be released during the next three months and speculates that they could be announced during AppleExpo opening keynote which takes place in Paris in September. Pricing should remain the same for all the three models.
