Adobe PS CS4 cross-platform upgrade

A friend from across the street

I’ve heard negative comments about Adobe’s support before, but on this, I’ll have to give them kudos. I just got the Mac version of Photoshop CS4 yesterday (Monday). Adobe were very responsive. I called on Thursday, asked for the cross platform upgrade, they gave me a link to the Letter of Software Destruction (LOD), told me to sign it, add my case number, and e-mail, fax, or mail it back to them. They went ahead and charged my card but were sure to tell me that they would NOT send the software until they had received my LOD.

As I don’t have a printer or scanner here in South Carolina, I waited until I got home on Saturday to send them the LOD via e-mail. On Monday, when I got back to my house in the evening, there was a UPS box on the front porch. No way could that be my CS4, I thought. I didn’t send them the LOD until Saturday morning. But, lo and behold, it was right there. Inside, the packaging slip said that they had sent it on Friday, the day after I talked to them. It shipped from Georgia, so they must have sent it out right away. They had even asked if I wanted express shipping, for and extra $15. I told them no. I’m glad that I didn’t! It couldn’t have gotten there any faster!

Anyway, now I have CS4.

Are there any tips that you’d like to share with me, as far as new features that I’ve just “got” to learn?
I know that there is some new black & white layer thingamajig, but I’m actually getting quite used to Lightroom’s tools.
