2) I need multiple environments, different OS's and all running at the same time. I think you are both right in that, Mac Pro is the way to go. But now I'm also thinking HP z620 (I know, not the right place to talk about that on a Mac forum). But I can get dual 10 core (i.e. 40 virtual cores) and 12 memory banks and it won't be that expensive.
But I love the Apple eco system, but at the same time tired and frustrated with the new iPhone 5S (getting a lot of reboots for some reason). And fingerprint sensor is awful at detecting my print (I work with my hands a lot so my fingerprint changes because of dry skin ,etc).
Do any of you use Apple + Other (android, MS) ecosystems? If so, how do you handle things like iMessaging, etc.
