Oh yeah a power failure during transfer will ruin your day among other thing but using a laptop with batteries I'll avoid that. It does take awhile downloading a 100 pictures and I usually leave the room, hold my breath and hope everything will be okay. But it's never let me down yet.

I spent 6 months getting comfortable with the Apple operating systems and I not going back. I still have never gotten over Windows 95. Apple is not perfect by any means but I like it now and I can get better tech support when I get stumped.

I carry backup camera too, in case the big one goes down. I have always had Nikons and have never had one break on me. Knock on wood.
