I'd screen for genetic disease. This is a difficult topic because even the smallest and most innocuous sounding opinion - 'I want my baby to have his Daddy's blue eyes yay!' - has all sorts of implications in an area of research that is basically an ethical minefield. I'm uneasy with cosmetic tampering, but I don't know if I'm uneasy enough to support making it illegal. When we get into areas like intelligence and athletic ability, though, and assuming we will one day have the means to tamper with these things (if we don't already) - that just opens up a big ol' giant can of differently flavoured worms. Actually so does the cosmetic stuff, just less directly. It goes right to the heart of questions about humanity and the 'worth' of the individual.

Parents in hot climates aren't going to be so tickled about choosing the obvious blonde/blue eyes option when their kid has a sunburn every day until he's 10 and skin cancer by 15.
That shouldn't really happen - the genes for hair and eyes are relatively independent within the sample taken. That is, they won't be selecting fair skin which would be more susceptible. All this will do is pick from the children that have the two (sets of) regressive genes present.
Still more likely to be fair skinned, and susceptible, but the kid would be equally so if they weren't picking out hair and eye color.
I'm pro-designer babies. None of us have been able to choose our genes and having someone who presumably cares about you do it is better than leaving it to nature. Anyway its the beginning of the path to the type of radical human augmentation I'm a fan of.
A US clinic has sparked controversy by offering would-be parents the chance to select traits like the eye and hair colour of their offspring.
The LA Fertility Institutes run by Dr Jeff Steinberg, a pioneer of IVF in the 1970s, expects a trait-selected baby to be born next year.
His clinic also offers sex selection. (BBC article at link)
This could become an interesting fashion trend. Since some will do it and some won't, it will be interesting to see how it affects society, and what kind of beliefs crop up around the ones that came into being this way. How these people are treated will be a good measure of how far (or how little) we've come as people.
There are definitely risks, but I'm so curious to see what happens... I don't like just leaving well enough alone when there's potential to see the effects of something more.
