If my son were an operating system, he'd be Linux. Linux isn't new, and babies aren't new...but this baby? It's the latest distro. Though it's built on the same kernel as it's predecessor, you should upgrade to this distro. It's entirely different and anyone who doesn't like it is old-school. Maybe you should RTFM.
If my son were an operating system, he'd be OS X. He doesn't have many features. There's iPoo, iCry, iEat and iSleep. But what he lacks in features he makes up for in simplicity. He's easy to use and has a very attractive form factor.
If my son were an operating system, he'd be Windows. The accessories you can use with this version are endless! The downside is that nothing's free and there's a million things to update. The stroller? Outdated! Buy a new one! That car seat is more than two years old? Security vulnerability - upgrade it! Your car won't hold all these accoutrements? You need a bigger drive!
What did iMiss?
