I commute on a train to work every weekday, and it's often a festival of portable devices. I often have my DS or my laptop. I see plenty of Smartphones, iPads, and of course other laptops and notebooks. There's the usual gaming devices (though it seems like most of the gaming I see is on phones and tablets as of late).
In my household, most everyone has laptops – and among my friends laptops are becoming more common over time. Netbooks are popular among many people I know, low-cost and portable.
It doesn't matter if it's work or if it's personal, portable is where it's at for geeks and progeeks.
