I had no idea that Snow Leopard was released nearly 2 years ago. This will be my first iMac purchase and I'm not sure if it is worth waiting a few more months for Lion to become pre-installed or if I should go ahead and purchase the refresh as soon as it comes out? The way I see it, since I'll be experiencing OSX for the first time, Snow Leopard should have everything I need and it will take me months to learn it. But 2 years seems like a long time for an OS release. It only makes me wonder if major features will be added. To those buying the 2011 refresh, the wait has been painful. Are you going to sacrifice waiting a few more months for Lion? Or will you essentially pay $129 to have the iMac early knowing full well you will purchase Lion when it comes out?
