Transfer songs and movies with copy and paste

Hello,
I have a new iphone and wanted to transfer things from one of my laptops to it, problem was this iphone was synced to my other laptop. You know the deal, you can't add songs to it unless you allow itunes to erase all other things or even more complicated solutions. Well, I opened itunes and went to my movies window. (actually so far i have only transferred small movies, not songs but am thinking both will work) I selected a movie and function + alt clicked and dragged down to "copy". Then I clicked on the movies list on my ipod and didn't even have to highlight anything..I just tried the command + V command. Voila. It pasted them to the itunes on my 'unsynched' iphone. (dragging to the window would not work, I'm sure we've all tried that"...it's a no loss situation since you're really just copying and pasting, with no risk of erasing or losing anything. Good luck and ha ha to Apple.
