Install my TimeMachine backup on my son’s Macbook Air?

My stepson just got his first Mac. I’ve had Macs for years, and have accumulated files, apps and utilities on my machine that I’d like to transfer to his. I don’t think I can just drag the individual apps from my computer to his, so I was planning to use Time Machine to put my last backup on his machine.

What pitfalls should I expect during this operation?

What pains-in-the-ass is my stepson going to face as he takes my computer profile and makes it his own?
