I have recently put 1GB more of ram in my powerbook g4 17" which has helped make it quicker but I am now contemplating fitting a 160GB hard drive as the current one is only 60GB or so. I will also fit a new battery in due time but is it really worth it? I was considering getting a new Macbook Pro 15" but after spending some time on the powerbook it seems more than capable of what I need it for (surfing the internet etc). My main issue is I will be going travelling round the world next year and will want something reliable so will the powerbook do me proud or let me down? Thanks.
