I am looking to purchase an external hard drive for my iBook G4, and could use some advice. There are so many products on the market, and I'm having a hard time figuring out where to begin. My primary concerns are that it be relatively affordable (under $150), small-ish in size (I live in a tiny apartment with limited storage space) and VERY user-friendly. (I mostly use my Mac for e-mail, surfing the web, listening to music, and uploading photographs from my digital camera--anything too technical is going to confuse me!) I plan to use the hard drive primarily for backing up iTunes (about 8,000 songs) and also a few photographs, so 250 GB or so is probably plenty of storage space. Any recommendations? Anything to avoid? Do I need something specifically designed for Mac (such as those produced by Western Digital) or will any hard drive work? Thanks!!
