I'm confused about the AC adapter that ships with the newer Powerbooks & iBooks. I have month-old Powerbook that came with a 45-watt adapter. Page 76 in the November issue of Macworld magazine says "current iBooks and Powerbooks ship with a 65-watt AC adapter that powers the machines and recharges the battery. If you've moved up from an iBook (dual USB) or a Titanium Powerbook G4, you can use the older machine's 45-watt adapter as an extra charger for the new Macs, but Apple doesn't recommend it: that wattage is enough to keep you working but not enough to charge the battery at the same time." I was talking to a friend who has a TiBook and he said his is 65-watts. So does Macworld just have it backwards, or am I mistakingly using an older adapter? thanks for replying!
