Except the screen. But it sounds like you like the Asus. Go for it! If you have to make a thread asking if you should keep a laptop, you probobaly will not be happy with it if you keep it.
But I'm scared about the Asus, too. It could be too heavy, too slow for the HDD, too keyboard crappy and stuff.
I hate how Apple just makes me mad with every MacBook xD it's all against me! LOL
If the cMBP had a better screen (matte but with normal res) I would have gone for it for sure, but in this case...
The problem with the Retina is ironically the screen! It is just bad not to have the possibility to view contents at full size. When I make a video I need to know how it looks at pixel-native res. The Retina scales everything! And for this reason it lags, too.
