In answer to the question...
No.
I work with computers on a daily basis, and have a range of draughting and 3d software at my disposal - but there's nothing quite so "present" as a model you can touch, feel and move your head around.
There's something a bit soulless about the views of ships made on PCs and manipulated by a mouse. It's like "early CGI" - too clean, too perfect. A physical model can give a sense of architectural mass, layout and form (along with grime and "use") that currently created computer generated ones seem to lack.
Maybe***, in the future, we'll have the software and the ability to make realistic ships on the computer: accurately model waves and seas, populate them with crews, generate all the black smoke we want - run a "virtual" harbour/battlegroup with the same acumen that the scale railway modellers want their circuits to achieve - but for those of us who've made models with hand/eye coordination and employed craft skills that are learnt or self-taught, there's nothing quite like it. For me, at least, it's a break from "pushing digits" during the nine-to-five.
I rather hope (types this technophile) it stays that way. After all, does seeing a print of a work by a favorite artist bring you anything like the same feeling as seeing the real thing?
That said I have used and will continue to use PCs to scale stuff, fair curves and check out dimensions/buoyancy before cutting. It'd be mad not too. And I have enjoyed seeing B&W photos of ships colourised by skilled Photoshop artists. Maybe if the storage is a problem, an answer would be to scale down things, store them elsewhere, or look to the more creative aspects of using a computer in the hobby?

***Reflecting on this - it's not "maybe", it's "certainly". Looking at the evolution of Microsoft's Flight Sim and where it is today, there's every likelihood that a Matrix-like world of virtual entertainment will become affordable and will find a place. But it's not there yet.
