live Preview

I wonder why people are upset over Canon's Live Preview feature in
their 40D and 20Da? If you don't like it, don't use it! It's as
simple as that. Just like when you were learning to use your DSLR
after graduating from P&S. Us Astrophotographers have been begging
the Canon folks to follow up on the 20Da's Live Preview and finally
they have. Do you know how hard it is to see a 10th magnitude galaxy
(or worse yet, 10th mag.Nebula) through an optical viewfinder VS. Live
Preview? It usually takes a computer program to make up for not
having Live Preview. Just do us (who use live preview) a favor and
use it or not, just quit complaining it's there.
