My younger brother's iBook is broken, and for Christmas my Dad wants to either have it repaired or buy him a new one. I believe that the broken computer is a mid-2005 1.33 G4. It has been broken for a few years, and when he brought it to the Apple store they told him that it needs a new motherboard. My brother thinks that they were wrong and that the problem is the power supply. Either way, I think that we're probably going to end up buying a new computer. My Dad knows next to nothing about computers, but he called me this morning and asked for advice on the situation. One of his tenants advised him to buy a netbook for about $250, and also found a refurbished macbook for about $500, but I don't know what model or from where. I looked on Craigslist and found a black 2.16 Core 2 duo macbook for $600, but that might be over-budget. Can someone please advise me on whether: repairing the power supply or motherboard on an iBook is something that would be worth our time; and if we can expect to find a decent macbook for around $500, and what we should look for. I really don't want to see him get a netbook or a junky windows laptop for Christmas, but that would probably be better than buying him a mac that turns out to be a lemon.
