Again, the Nostromo is a space semi truck that looks like it was made before any of the crew from Alien were born. The Prometheus is an extremely heavily-funded scientific research vessel. Of course it's going to have better technology.
Like 005 said, the Nostromo is probably older than the Prometheus, too.
The only problem I have with that excuse/reasoning is that it still leaves quite an unbelievable technological discrepancy between the ships. By that same logic, if I were to compare a garbage truck built in 1960 to a 2012 Rolls Royce, there should be a dramatic difference in technology. Sure, there would be advancements and refinements made in that time gap, but the the basic technology would still be the same. The Rolls Royce may look/handle/feel nicer, but both vehicles would have a windshield, steering wheel, tires, drive shaft, etc.
I would completely buy into the Prometheus' tech if it were comparable to that of the Nostromo's -- say, LCD or OLED flat screens with touch-sensitive controls -- but 3D holographic projections? Not even the same universe as Alien as far as I'm concerned. The only way a gap like that would be plausible in my mind would be if the Nostromo and the Prometheus were made over a century apart or if the latter was built with alien technology. I doubt a century-old ship would still be in service, and there's nothing to suggest that the Prometheus is anything but a man-made vessel.
Like Asterisk8 said, I'm still eager to see this film, and will judge it on its own merits, but aesthetically I really do wish it were more in line with Alien.
