Following on from yesterday's blog I propose an experiment. Totally anecdotal and unscientific, obviously, but I want to find out whether my theory about PSP being the more popular handheld console to be seen in public with, despite the DS selling more, is true. So, post in the comments if you see a DS or PSP being used out and about and I'll tally them up next week. In the meantime I'll do my normal thing of taking both with me and using the DS if I fancy playing a game and the PSP for watching last night's TV/listening to music. Oh, and no fictional sightings please, this is serious stuff. Honest.
