No arguments from me as a pretty happy Acer user.. if we can control
grain-aliasing/noise on negatives,
I just wanted to mention to any Acer Scanwit clients and others who want
to provide suggestions and guidance to Acer on new filmscanner products
or features, that Mr. Honda Lo contacted me via email and seems
genuinely interested in feedback from end users, particularly about
software

Empirically, it's unknown. The misregistration of the separate IR pass is

I had assumed that VueScan and other scanner software already did black and
white point compensation, but I think you may be right that they do not do
black point compensation. I have done BW compensation for area CCD cameras
I use at work and it greatly improves the uniformity.

I can certainly do so. Every few days I scan another batch. Next time I'll
try to remind myself to grab a stopwatch first.

Well, it is most definitely slower. And Ed Hamrick says

Probably the extra pass for IR is more coding than is justified, since
no other scanner requires one.

Not on a Mac, but it's not platform-dependent (it's SCSI--G-4
notwithstanding). And yes, it's competent; the 2740 is an upgrade from the
2700S. But keep

As for me..(amateur opinion follows!)
I have the Acer 2720, and I like it very much. Neutral, slightly
undersaturated colors (a very slight cyan/blue cast on mine, easy to
correct). Good shadow detail and very little shadow noise
