Have a new ibook/500/256/DVD machine. I really like the machine, but the AC adapter plug has been resized and so the prior car/airplane adaptors for the old ibooks and powerbooks no longer work with this machine (or the new G4 Titanium, I understand). Does anyone know companies that manufacture these adaptors other than BTI and Belkin. Thank you for your help. These two companies have not produced an updated product yet.<br><br>
