what's the difference between the 4490 and the v500?
is it only the light source
the v500 is 20-30GBP more expensive than the 4490
is it worth?
i will probably use it with either vuescan or silverfast.
thanks for your answers

The light source is now LED which should decrease startup times, but in terms of scan results, I don't know that it really improves things.. If anything, I think the difference would be in the lens since it supposedly is rated at 6400 dpi (which is just marketing hype).

how long will it take for the 4490 to start up?
