In high school I was already keen and skilled with building desktops from parts and they had some related classes but they were all canceled. The resources to improve my technical knowledge simply were not there.
With that being said, I think Raspberry Pi can be a real shot in the arm in education. Ultimately, it becomes how it is marketed, having proper and inspirational teachers, and building a community to interface with educational market as well as personal. A delicate balance.
My personal interests are how ARM/RISC is advancing in the face of Wirth's Law, what I mean is the following:
You take a look at your typical daily use-case and ask yourself "could I get by with a less powerful computer?"
Then take it one step further, technically and ask yourself "Why does my browser/text editor/software x take up so much memory? Was it designed efficiently?"
A good thought experiment or the Pepsi Challenge is asking yourself "Could I perform my daily computing tasks on Raspberry Pi or similar device? How about a device twice as powerful and with more features and I/O? How about a device three times the computational power? How about a device n-th powerful as RPi with x set of feature?"
If you answered "Yes" or "For a majority of the tasks, yes" on a relatively low n-th count, you ought to be amazed. Amazed at how far ubiquitous and affordable computing has come and has yet to come and also amazed at the bloat of software due to API middleware, software laziness, and math ignorance (algorithms/optimization).
So the triple constraint for usage of Raspberry Pi or n-th iteration in this regard boils down to:
Form factor (size), I/O + features, power consumption (all related to one another)
Overall computational performance
The important thing Raspberry Pi Foundation is doing is being vendor for a product of this size, cost, and type.
But that was a large digression regarding my thoughts on Raspberry Pi and why it is exciting beyond educational purposes.
