Anyone know how these are going to be priced?
AdaFruit have been selling a $35 PiTFT 3" touch screen - which is useful as a small control screen but not for making piPads. (well, maybe piPad nano...)
Raspberry Pi Founder Shows Off Incoming Touch Panel for Making DIY ‘Pi Pads’

Re: Raspberry Pi Founder Shows Off Incoming Touch Panel for Making DIY ‘Pi Pads’
#22Since the Pi is meant to be for education, what I think would further this goal is to turn the Pi into a graphing calculator as a replacement for the TI series that is currently required in many high schools / colleges. So you would take the basic design, add the case, battery, button pad, cheap screen. Think of a calculator that has the Pi's SD slot, HDMI, USB, GPIO, etc ports. When used in class or on tests, it can…
The graphing calculator is a very stable tool; the raspberry pi is an exploratory device.

The reason it's so entrenched at the moment is, I imagine, standardisation--which is why a custom raspberry pi solution would not be suitable. As an side, I'm not entirely sure why a graphing calculator is even required anyway. I never used one once…
> I never used one once in my entire school curriculum, and don't feel like I suffered for it. I'm glad someone else said this, because I wasn't going to admit to it. I got through 4 years of high school math and science, and four years as a CS major/math minor and I don't remember ever using anything other than the permutation/combination functions and some basic graphing. The TI-83 was much more important in gettin…
Creating programs to do the same steps over and over once I understood it was the biggest benefit I got out of my graphing calculator. However, having a larger screen with a scroll history was a close second, so even just using it as a standard scientific calculator with a large screen made it very useful to me.
My high school didn't require a graphing calculator though, and most of the class didn't have one as I recall.

Most people I know buy second hand TIs which aren't expensive. They are around the $20-50 (GBP conversion) mark here in the UK. The Pi is not exactly a good proposition for a calculator either based on form factor and power usage. Also you really do need a tactile input system for calculators as they help avoid costly and confusing mistakes. I'm not sure why there is so much hate for TI to be honest; they are very fu…
I'm not sure there is really hate for TI calculators, but rather a general sense of "wtf are we paying for" when they've been the same spec and the same price for 20 years. No one really thinks they're bad calculators, but really they should be $20 by now, with a $100 color version or something to round out the high end.
There's an XKCD for that: http://xkcd.com/768/

#25From the picture it seems to be a 7 inch, 1024x600 touch panel, same as in the Kindle Fire original.
I believe, based on descriptions of the prototype, that it will be 800 x 480. That seems rather small, but they want to hit a price point (< $70), consistent with their primary mission of providing an affordable educational system.

I believe the target price is "under $70".

7" WVGA TFT panels are flooding out of Asia for dirt cheap now, that would be my guess as well.

#29Cool! Back in 2012, I got impatient and put together my own resistive touch screen for the Raspberry Pi: https://www.youtube.com/watch?v=uwEwHFglq8M. I just got a small LCD, a resistive touch panel, soldered up a microcontroller, and wrote a simple kernel module (https://github.com/osandov/raspi/tree/master/tsc2007) to get it all working. Unfortunately, I never really got around to documenting how I did it, and it looks like this makes it obsolete, but it's all for the best :)

I'm actually in the same boat, I was in HS back in the 80's. But after raising 2 kids that seemed to need a new calculator for school each year (either due to a new model, or they lost the one from last year) I kind of figured making it a pocket computer that hooks up to their TV would make them "stick around" and be worth the price more.
I wasn't thinking so much as turning the actual Rasp Pi into a calculator, but instead the foundation making a decent calculator that can also fill the function of the Pi (HDMI/USB/SD ports, runs Linux). Figured they would have enough visibility to make the PiCalc the next standard (or work with someone like Ti to make a PiCalc).
It just seems a waste to spend so much money on what I consider junk (single-purpose calculators, and for kids who aren't into math they are useless outside of the classroom). Although as calculators, the Ti's aren't really that bad, but my preference leans to the older HPs.
