I know it's easy to advise someone to max out their Mac Mini or iMac, but to be honest, anytime I've done this with a Mac (mac pro, MBP, etc), it's never felt fast to me. And I've always ended up regretting what felt like a waste of money and zero gain in performance. I'm back and forth on either getting a new Mac Mini or a new 27" iMac. Using it for both general purpose stuff like email, Office, watching movies but also Lightroom and Aperture work. My thinking with Mac Mini is if I bump to the i7, is it really gonna matter between the the choices in processor speed? Do I really need 16gb of RAM? Will I truly benefit from a Fusion drive once I pop a 200GB iTunes library and a photo folder of 155GB - especially on a 5400RPM drive? Plus it leaves me to get a monitor. I hate the thought of getting a Mac Thunderbolt Display now and maybe in a few months comes the replacement version seen on the new iMacs. The benefit I see with the mini is when I'm over and done with it, I'll just incorporate it into my home stereo gear as a stand alone music server. With the iMac 27", it's also a question of which processor really matters and how much ram and fusion or not. But I'm worried about the wait for delivery plus read a lot about iMacs not lasting very long before repairs are needed. I'm in need of help.
