Upgrading RAM in MacBook and iMac?

[Rotorhead1969]

I have both a 2008 iMac aluminum body iMac (currently with only 1GB of RAM) and a MacBook Pro, currently with 4GB of memory. I know the 4gb sticks were super spendy when these computers were brand new but now I can get a pair of 4gb sticks for $235 through OWC, so what I'm wondering is this. . .
Could I split my MacBook memory up and put one in my iMac and keep the other in the MacBook and then add one of the new 4gb sticks to each machine?
Would the Macbook memory be compatible with the iMac (as this generation iMac actually uses laptop sticks)?
Would it work?

This would give me two screaming machines with 6GB of RAM and an extra 1gb stick I could use as my iPad bookmark

Well, it depends on what models you have. Different revisions used different kinds of memory. I am fairly certain that your iMac uses DDR2 RAM, but I don't know what kind your MBP has. If you posted screenshots of your "about this mac" for each, that would be helpful.
