You can do both. My point is that most of the ports and features they removed really cost nothing in terms of weight, and so aren't really engineering tradeoffs in a sense, but rather design tradeoffs (i.e. thinner). In the feature/weight space, they are not even close to the pareto optimum.

Personally I find wireless anything to be a persistent pain and not worth the trouble, but since it costs almost nothing to add, I'm totally cool with adding it. Maybe in 10 years it won't suck.
