A friend of mine is buying a new powerbook, and needs advice on refurbished products as he is considering buying one. So my questions are: Has anyone here bought a refurbished product? Do refurbished products go wrong? Are they more or less reliable than new products? Is there any noticeable difference between a refurb and a new one? Any help is appreciated as i have never used a refurb in my life. But in particular help from the UK, as we are not exactly known for our reliable retail sectors. cheers.
