My mid-2007 24" iMac has been the best desktop I've ever purchased. 100% reliable all these years. It's old and needs to be replaced. I was certain 2018 would the year to do so with a new redesigned 27" iMac, but nothing was released. I'm either going to wait for the 2019 iMac or be tempted by a laptop or a mini. I love the big screen for watching movies and youtube. This is a true personal pc, nothing heavy duty being done. the iMac serves as an iTunes server too. Can I reproduce the experience with the Mini or MBP? If yes, at what cost?
