I am brand new to the Raspberry Pi world. I have been curious about the computer for as long as it has been around, however, I never really pursued my interest in it until very recently. I recently attended the IET event (in the Manchester audience) at Manchester Metropolitan University and about halfway through, decided to get my iPhone out and ordered a Pi there and then.
In some ways, I totally missed the point of the Pi, or, more specifically, thought the point of it wasn't relevant to me (at least not directly.) I am a sixth form tutor. I teach A-Level computing and BTEC Software Development. I thought that whilst the Pi was cool, we were already teaching kids how to program in C/C++, Objective-C, C# and Java. The Pi, whilst cool, wouldn't allow us (so I thought) to do anything new or different. I acknowledged it was a great idea to get kids into programming. But my students already were, so no real point.
I underestimated the incredibly cool, immediately engaging form factor. My students love the Pi. It's a great thing to work with. The ability to have it interface with things like Arduino will be very important to us over the foreseeable future. It's going to be our "next big thing", bringing electronics to a classroom environment where software is usually far and away the king, it'll be great to show students the hardware in a way more engaging way than the typical "a CPU does this, RAM does that..." etc.
Our focus has been on developing iPhone apps with Objective-C and the students have loved it. We've since added Xbox 360 games dev with XNA and C# and we're about to add Unity, since Nintendo's announcement that Wii U will support it (this is on the BTEC, the A-Level computing is unfortunately much older and much more limited... though it is changing) and we'll definitely be looking at adding Pi/Arduino onto the course as well once we have found a balance.
Hopefully, I'll be able to contribute stuff as well as ask a billion questions.
