I currently have a 15" rMBP 16GB RAM 2.3 i7 and I am trying to decide between getting a Thunderbolt display to hook up at my desk with this or just get the RiMac... I think if the TBD was 5k then it would be no contest but at the moment the resolution wouldn't match with the current TBD and I also don't think 1000$ is worth 4 year old technology. That being said it doesn't look like the TBD is getting updated anytime soon (or is it?) but spending another 3k on a decked out iMac is a big decision too. So that being said, are the 5k RiMacs worth it, are they awesome machines or are they having tons of issues and I should just keep waiting for now? Thanks!
