For me, using PNG images has a positive consequence. I use Fireworks  
on the Mac to design my interfaces, which are typically covered head- 
to-toe with graphics.  If I import calibrated-by-eye, perfectly  
contrasted pngs into MC/Rev they appear much darker - even on the Mac  
-  which is a rude awakening if I've been concentrating so much on  
design that I've forgotten about gamma! I can set the Fireworks  
window next to the Rev window on my Mac desktop and see the  
difference. Either Fireworks is setting the PNG metadata so that Rev  
displays it with Windows gamma, or Rev is using Windows gamma despite  
Fireworks' setting. Either way, I'm getting Windows gamma on the Mac  
in my user interface which means that its appearance is the same on  
both platforms. And that's all I care about!

"But wait"! you say, "How can you design in one gamma for display in  
the other?" No problem.  Fireworks has a "View Windows Gamma" menu  
item that lets me design on the Mac while seeing Windows gamma. It  
seems that in the past the situation was different - I used to  
struggle with the disparity in gamma as Chip describes. But in the  
last while (a year or two?) though a couple of version upgrades of  
both Rev and Fireworks, the Windows gamma situation has worked in my  
favor and I pray it never changes!
