FOr all of you enterprising iBook 700 MHz owners out there like Blakespot, check this out: http://www.powerpage.org/story.lasso?newsID=9606 Apparantly, the ATI Mobility Radeon chip inside the iBooks supports monitor spanning, and Apple has limited the iBook's functionality to keep a greater separation between the iBooks and TiBooks. If you check ut ATI's site, you can see that the chip clearly supports dual monitors... http://www.ati.com/technology/hardware/mobilityradeon/features.html Also, if you check out the specs on older TiBooks (the first with gigabit ethernet runningg at 500/667 MHz) you will notice that they also had ATI Mobility Radeon chips. So, if they supported monitor spanning, one would think that this is inherently possible with the 700MHz iBooks. http://www.apple-history.com/pg4_giga.html Some guy in Germany transfered his hard drive contents from an older TiBook to an iBook, and discovered thi by accident. Anybody out there want to give it a try?
