Ian is 11 and wants to know if he should buy a MacBook or build his own gaming computer. Leo says that building a computer is a fun project, and a great learning experience. But if something goes wrong, he'll have to be his own support. If he buys a computer, then he'll have a company to support him. Leo also says that running Steam means that many games are ported to the Mac, but most gamers are on PC, and that means Windows. But if he's planning on doing other things like getting into video editing, then Leo would recommend the Mac.
