I am looking for an iMac(I think). I have an iPad and a rMBP 13" 2015 I use as my main computer. I do a lot of data analysis and work in spreadsheets a lot which would be better on a big screen, plus it would be better just for personal browsing/email/youtube. Trying to decide which iMac would be best for me, I plan to keep this for a while and get good use out of it. I have thought about the idea of getting an external display and a thunderbolt 2 dock for my rMBP but I think I would rather have a separate device. I guess another option would be to get a 27" 4k monitor and a mac mini, but they haven't been updated since 2014 so I don't want to get something that's already 3 years old. Plus, the cost of that would be around $1,000 already because I wouldn't get the base model mac mini.
