I have a 2008 2.4 GHz MacBook MB403LL/A that works just fine. I also have an iPad 3 that I have been using quite a bit lately. I can trade in the 2008 MacBook at Best Buy for a GC that would almost entirely cover a base 2011 Mac Mini. Should I keep pushing the old MacBook? Or trade for a Mini and then rely on the iPad for portable needs? Thanks!
