I remember reading benny's post that Arc fell short compared to Incredible S based on his short hands on during the preview. I am interested to know the difference as well... do share!

I will be writing a review and comparison in my blog  between the two smartphones . Still have not posted it as I have yet to do night video recording comparison - past few days been raining at my place at night. Anyway I have been using the ARC only 4 days vs 3 weeks  on the Incredible S. My impressions till today remain the same:

Camera/Video recording : Arc is way ahead very much better . ARC  is lighter , display slight brighter and build looks classier

Refer to the Incredible S thread at http://forum.lowyat.net/topic/1792466/+1680 : I have posted camera shots and video recording between the two

Other than above positives, on general performance  it loses out to the Incredible S in most areas : apps installation speed, apps launching, UI slickness and smoothness, UI interface, browsing etc .  I will support these with actual numbers I have assess in my blog post
