I'm in a pickle. I've got a 15 inch MBPr (early 2013), which I love, but I need more screen as the 15 inch is becoming frustrating. Totally torn between buying a 27 inch iMac or simply adding a decent 24 inch monitor to my MBPr and using that as the primary screen. Clearly pro's and con's to both, second screen is way cheaper, I'll lose resolution, 27 inch iMac is a lot more money, more powerful and the screen will be better. The additional power is here nor there for me, the resolution will make a huge difference, but I'll be paying for it. There's a thread in the hardware forum about it. Anyhow......as per thread title. If I go down the route of the iMac I'll keep the MBPr for client vists, trips away etc, my missus was going to bag it but that's not happening either way. It is possible to run the same email accounts on Mac Mail on both Apple machines and keep them in sync? So emails replied to on one machine show the reply on another? Works this way on my phone (Gmail on an android - don't like iphones), but not sure if a second Mac can be tied in the same way? Ta!
