I was curious, I just bought a new iMac which came with Mace OS X Lion and when I am checking in the App store it says installed is it possible to download Lion so I can install it on another Mac? I was able to do it with iLife 2011 edition easily because this came with my new iMac so I was able to updated on my other Mac (which is installed with Snow Leopard (10.6.8). Yes i did try the Option key on app store all it does it switches back to $29.99. It is just odd that I can not download it again on another computer that does not have Mac OS X Lion but I am able to update iLife 2011. Please, if someone can explain the situation what would be the difference downloading and paying $29.99 and buying a new iMac which comes with Mac OS X Lion and not being able to download again so I can install it on different Macs that is like double dipping trick.
