Hello all, I've been a PC user my entire life and recently grown accustom to the MAC World. I bought the Unibody Aluminum Macbook last night, 2.4Ghz- I'm still getting used to it but I like it, the only issue I have so far is the BATTERY LIFE! I opened it up for the first time, it was half charged- I used it for about 5 minutes than plugged it in until it was fully charged and kept the power cord in the laptop over night (while it was turned off) anyway, today I've been using it wirelessly for the past 15 minutes and the battery life has gone down from 85% to 75% in this 15 minute or less period. The website says this has up to a 5 hour charge. All i'm doing is surfing the web and listening to music. Should I be worried? At this rate the charge will be gone in an hour or so.. PS* I haven't changed any of the energy saving settings.
