My trusty and beloved G4 iBook (12 inch, 800mHz), is not quite doing the job any more. The battery is nearly depleted, even when fully charged, and I'm constantly running out of space, with only a 40GB hard drive. (I already keep my music on a separate external hard drive, but this is a pain.) I was ready to buy a new MacBook or even MBP, but Apple seems to be working through some quality control problems. I use my iBook as my sole computer (for syncing with my phone and ipod, downloading music, surfing, photo downloads while traveling, work conferences...). I really depend on it and won't take a chance on buying a faulty machine. I found a site that will exchange the iBook's hard drive, and also sell me a new battery. Should I go this route for a 3 year old iBook, assuming it will last for at least another year? The new MacBook has certain pluses, though, such as the built-in iSight, built-in bluetooth, the ability to run Windows, and support of a larger external display. The only alternative I can think of, buying a desktop, and waiting until the quality control problems resolve to get a new laptop, is a pricey route to go. It's really important to me to have a dependable computer, but I want to do it in a cost-effective way, (and not add too many more gadgets to my already crowded apartment).
