I've been looking into buying a new hard drive for my ibook g4 & from seagate to WD to Samsung and prices from 50 to over 500, I'm utterly confused about what is best. I'm giving this computer to my 66 year old mom who will mostly use it to surf the web, email, watch videos, etc. Nothing real demanding or sophisticated. My main concern is that it's fast enough to handle streaming video or audio & that it be durable and as long-lasting as possible. (also I'm executing a secret agenda to convert her to a mac love -- my dad filled her head w/ pro pc nonsense for years & she's still wary of how cute macs are & believes they may just be toys for kids ) Does anyone have any recommendations for a good HDD?
