Next month, my G3 iceBook will be turning 4 years old--and still running strong. I'm on my 3rd hard drive, I've had to replace the reed switch, fix a trackpad issue, upgrade from Puma to Panther, and even ran windows via Virtual PC. And you know what? I think this little machine can go for another at least 2-4 years. In fact I do plan on doing some minor additions to my machine. I plan on upping the ram from 384Mb to 640Mb. I found some memory at newegg.com that I might pick up. I'm also thinking of getting a set of speakers, perhaps the JBL Creature II's, to compensate for the tinny iBook speakers. I don't plan on buying another mac until at least the rev B Intel Powerbooks are introduced--and that might be a very long time. So how old is everybody else's current system?
