I've always had silver since I Got my 1st MacBook in 2009 so was always jealous when they started doing the different colours.To me it's always silver as it wears the best over the long term
I'd go insane with nicked up paint and worn edges, etc
I just got the space black in April and it looks great but for me it does smudge too much compared the old faithful silver.
I feel like the silver is quite a classic look now so if could choose again I'd go silver.
