Unfortunately you cannot just scale it down to 50% - it will not look good.

Maybe there is another way around?

in css? i think it will be okay, but just will result in bigger files and more network usage, especially for mobile 3G/4G users...

Nah I was talking about resizing in Photoshop. That would not work. I think he was talking about doing the full retina web design in Photoshop and just scale it down by 50%. That would not work. I guess it will work with CSS3 for the different elements.
 
KimHansenDK there is some tricks that can be worth considering, but as we said before, 99.9% will never see this and in main situations it will be more work or just slower sites for most users.

Maybe the right way is buying something like 27" ATD and use it at home for designing, and for other things like coding use onboard screen...
