I've been eyeing up a Thunderbolt Display for quite some time. I quite liked the idea of docking my MacBook Pro to it as an external display and having the ability to access external drives connected to it. However the need for a media server for my house has made me rethink things. At first I was considering a combo of Tbolt Display + Mac Mini. But swapping this for an iMac (27 inch) seems like the better option given that it's cheaper and if it does the same functionally - happy days. Along with this, my other half has been talking about buying an iMac for quite some time and therefore I may be able to save some money here! The main tasks that I'd need to do are as follows: 1. Connect MBP to iMac via Tbolt port to use as external display (is it possible?) 2. Easily switch between MBP on iMac display to the actual running iMac (How?) 3. Function as a media server (to Apple TVs) and general 'hub' for content via iOS devices and laptops (comments?) Which combo would you prefer and can you think of any pros/cons to each? Also, can you provide any insight on which hub may use more power (iMac on but display off vs Mac Mini constantly on)?
