Hope someone can help shed some light... just a bit confused. Have to buy tomorrow (Monday) so fast answers much appreciated. My question is mainly regarding connectivity and bus speed. I'm needing a new laptop for travel, shooting on location/studio and working from home. My workflow is shooting tethered with either a Phase one p30+ via firewire 400/800 or a Canon 5dII via usb. Cameras are never tethered at the same time. I'm shooting into Capture Ono Pro and also running multiple processer hungry apps at the same time such as PS 5 as a norm. I also connect to an external monitor via DVI (eizo 27" flexscan). A two external monitor option would be ideal. That in addition to an external drive for backup (firewire). Additionally I also run a QNAP server from the studio connected via ethernet which I would like the option to connect to if needed from time to time. With the two new model options I'm a bit thrown by the new thunderbolt and what seems like limited connectivity with the new rMBP. Having the 800 and ethernet port seems like a better option. Also I know that having the thunderbolt but not running thunderbolt devices won't give you an increase in speed but is the bus speed still the same in the two models? I guess my question is will I be kicking myself in a year if I go for the non retina option body and can I get a multiple connector option for a single thunderbolt port? Screen option for the non retina would be hi-res anti glare, not really fussed at this point about the retina, more then likely as I've not seem the benefit and also use external displays for my editing. Thanks in advance.
