Parents, if you bought a video game system for your kids as a holiday gift, be sure to crack it open, run all the system updates and get any games installed so it's ready to plug-and-play as soon as they open it.
This message brought to you by (admittedly fond) memories of watching my dad make DOS boot disks all afternoon on Christmas.
@tangocharlie I would think this applies to phones, too. Take the person's phone, they can live for a day or two, put the card from the old phone in, make sure it's activated. Then surprise them with it on Christmas morning, all ready to go! No need to fight to get it activated on Christmas Day, then!
