at the moment i own a dualie powermac coupled with an apple cinema display aluminum 20" it's getting to be a slow computer im thinking about buying the iMac aluminum refub for 999.00 or should i purchase an mac mini refurb? i already have the cinema display but i don't' think that the mini is worth what the price is but the imac is almost too expensive. would i see a big difference in the mac mini power and imac aluminum 2.00ghz? in the long run would the imac or mac mini which one in 3 years (probably how long i'd have the computer) be worth more? is the iMac really worth 1,000?
