I am thinking of switching to a Mac Platform (MacBook Pro) and tether a Imacon Ixpress 528C back to it (through the imagebank). Does the powered Firewire offer enough power for the back? I have heard that this was the case with the old MacBooks but things may be different now?
I don't recall the 528c causing power issues on Mac laptops, but I may be forgetting something. Worst case, you can put a charged battery on the Imagebank while it's tethered and that should prevent any power issue from cropping up.
