I love my mac for handling its programs that handle photos, and music and it's rock solid where I don't have to reboot the thing for weeks at a time. However, in Apple's pursuit of thinner and lighter, they are no longer the work horse I need to do my work. My last MacBook pro was 17 inches and had an i7, but you can't get that size anymore... and I loved that size as I could work anywhere in the house or take it on the road when I travel and do some sculpting. However rendering on thinner machines causes the fans to kick into high gear when I'm not wild about and reduces the lifespan of my machine. The GPUs on macs have always been a big fail, never enough for what you need. I'll use it for graphics though, but my workhorse is a 6 core i7 that's watercooled and has two NVidia graphics cards in it. I bought that when I was ready to buy another machine and walked into the Apple Store, saw absolutely nothing that met my needs and walked out the store with an ipad and placed an order on Newegg for PC parts. So for future macs I'll probably downgrade to either a mini to stream music and videos, and if I usually travel with my work laptop which I installed zbrush and my ipad, though they'll probably switch me over to a surface pro by summer if this pilot goes through.
