I read technology news. Every major consumer electronics manufacturer has tablets due in this period, and many of them are around $300 to try to compete with the iPad on price point. Meanwhile, if I recall correctly Apple will probably report that the iPad has shipped in excess of 28 million units. At that rate of adoption we will probably see something like 1-2% of Americans own *just* iPads by the end of next year. Depending on the success of alternatives like Samsung's Galaxy Tab and offerings from ASUS, HP, etc, we could see that rise as high as maybe 5%. So by the end of 2011 we may have 1 in 20 Americans own a tablet device. Tabletop gamers tend to adopt technology faster for cultural and demographic reasons, so I could see easily doubling or tripling this number among tabletop RPG players for 10% to 15%. That assumes a relatively steady rate of adoption and not some kind of near paradigm shift in casual computing that some analysts are predicting.
