im about to buy a mac mini should I wait for the new release if there is one or get the current model cheaper and go for the higher spec i7. the i5 is coming down in price in the uk . got me thinking whether to wait for new release and get the i7 when that becomes cheaper. what the graphics like on them? are there any common faults or are they just very good little machines im hoping for ?. and do they run hot ?.
