I'm sorry if this has been asked, I just need some advice from knowledgeable persons, such as yourself... We have an iBook, from 2004 I believe. STILL running on Mac OSX 10.3.9. We can no longer get software updates, our flash player/adobe no longer is compatible with just about everything, and I'm getting rather frustrated. We need a serious update. Would you invest in an update to whatever system we can run on, or look into a new computer altogether? Obviously we don't want to spend a lot, but which is more economical? TIA!!!
