I have had mine for about 3 months. I really give my machines a good beating since I use them alot and this one hasnt even flinched. Logic board failures, Random shut down syndrome, and all those things havent shown up on my 2 ghz macbook. The staining of the handrests has been fixed on the white models, the black models don't stain obviously. My uncle has a 19 inch iMac and he says its really amazing too, fast, reliable, etc. So it depends if you'd rather be mobile or not (i.e. laptop or desktop)
