Ladies and Gentlemen, I am in desperate need of some help here. I'm eligible for a work computer upgrade and have come down to 3 options that I really can't decide which is the best bang for the buck. I was waiting to see if anything updated at WWDC but can't wait any longer. I turn to you. I'm an attorney and spend almost all my time on my desktop usually having multiple documents open at a time and working off Word, Excel, and Acrobat constantly. No real heavy photo, video, etc. Just tons of documents and big .pdfs. I use Office 365 for my main apps and Dropbox for cloud storage. I have to submit this to a committee who decides. I'm pretty sure anything over $2k will get rejected and $1800 is the most they have spent. These are all new via Apple BTO except the one model available as a refurb. Mac mini: $1,477 2.8GHz Dual-Core Intel Core i5 (Turbo Boost up to 3.3GHz) 16GB 1600MHz LPDDR3 SDRAM 2TB Fusion Drive Intel Iris Graphics 27-inch iMac with Retina 5K display: $1,899 (I can refurb for $1699) 3.2GHz quad-core Intel Core i5, Turbo Boost up to 3.6GHz 8GB 1867MHz DDR3 SDRAM - two 4GB 1TB Fusion Drive AMD Radeon R9 M380 with 2GB video memory I would go out of pocket to upgrade the RAM later via Amazon. 21.5-inch iMac with Retina 4K display: $1,999 3.1GHz quad-core Intel Core i5, Turbo Boost up to 3.6GHz 16GB 1867MHz LPDDR3 2TB Fusion Drive Intel Iris Pro Graphics 6200 I would probably offer to go out of pocket a little on this model I'm leaning towards the 27" but wanted to see if the more educated had any thoughts.
