Search as much as I can but I can't find the answer to my questions. I have an iBook G4, about 4.5 years old: Processor: 1.2GHz PowerPC G4 Memory: 1.25GB DDR SDRAM OS: 10.4.11 Mostly I use it now for web browsing and the occasion word processing. Initially I bought the machine while studying a Photography degree, which is now complete. Occasionally I use Photoshop CS2 on it. Increasingly I am noticing that the machine is slowing down, firefox now takes longer to load, as does Photoshop. I'm considering purchasing a 13" MBP as a replacement, but would rather try and get the old G4 running better rather than shell out about a grand. The question I am wondering about is, how long can I get my iBook to last, and how can I get it to run faster? I tried to look for an answer over the expected lifespan of the iBooks, but there's not much information. Any advice would be greatly appreciated.
