I've had my PowerBook G4 for just over 2 years. It cost me £1,450 and would be considered a professional laptop computer. However, in that time there has been a number of problems: - The 'R' key popped off after a matter of weeks but was not covered on the warranty - that cost me £28. - Dust is managing to get in behind the LCD display causing shadowy specks. - I've needed to reinstall the Mac OS on four occasions. - After just a year, the internal fan started making a loud rattling noise - infuriating! - My HD icon recently vanished from my desktop so will need to reinstall a 5th time. - iCal suddenly lost ALL my events and I never got them back. - One of my USB ports works intermittently. - For the last few months, the LCD flickers and sometimes goes altogether... and this is the final straw. So I need a new computer - but will I buy a Mac? Probably. Will I buy a MacBook Pro? Probably not. Will I consider returning to Windows? I feel I have to. For a professional laptop to get such light use and have so many problems is unacceptable. I saw my PowerBook as an investment - if I pay more I'll get a machine that will last me longer. My crappy Toshiba PC laptop lasted me well over 4yrs. Bad show, Apple.
