So I went to my nearby computer store that has Apple products displayed to demo and try out. I noticed they did a clean up and reorganized a bit. Besides that, they also had their "demo" models for sale, quite a few of them. Two demo MacBooks were also for sale, Core 2 Duo but the low end kinds. When I went to open them up to check them out, the casing around the keyboard/keys was greyish, not the normal white. I was wondering is it normal for demo models to have a grey-tint casing since many people touch them or is this how they come? I'm guessing they perform just as well as any new MacBook, just cosmetically.. their not up to par. Thanks for reading!
