I've been using PCs since the DOS days in the early 80's. I have never really used a Mac more than a few minutes at a time over the years. I switched to iPhone last year from Android with the 5s and upgraded to a 6 this year. I also switched from an iPad 2 to an Air 2 this year. Obviously, I'm staring to get locked into the Apple ecosystem and I have been thinking about switching to a Mac and running Parallels for the Windows programs that I need to use. I stopped by the Apple Store today and looked at an iMac (both a 27" standard and 5K) and they were both fast and smooth as butter. I even sort of liked the Trackpad, which I thought I'd hate. Before I fully commit to a $3,000+ iMac I was thinking of getting a 2012 Mini and upgrading the RAM to get used to the switch. Would a 2012 i7 Mini upgraded to 16GB of RAM be anywhere as fast and smooth as those display iMacs were?
