After another dead third party charger, and a dying hard drive, I think it might be almost time to retire my powerbook. Also here in Canada it's much too expensive to pay upwards of $70 for an oem charger. Should I save up a few hundred dollars and just get a 2006/2007 Macbook pro? I need a new laptop in a few weeks so I'm not sure if it's worth reviving my already ageing powerbook
