This can't happen soon enough for me: https://www.indiegogo.com/projects/pi-top-a-raspberry-pi-lap... .. but then, this is also pretty usable for the same purpose: http://www.raspberrypi.org/forums/viewtopic.php?t=6747

You can buy this today: http://www.lilliputuk.com/monitors/hdmi/668gl/

Which costs $270 to be shipped to my house. That 10x what the Pi itself costs.

This really should be the next thing the RPi team tackles, IMO. It's nice we have this great cheap computer, but trying to find a screen to plug into it is terrible. A computer monitor or TV is fine, but both of them draw too much power and are far too big and stationary. And have you seen the prices of small HDMI screens? I can buy a 8" Windows tablet, full PC mind you, for the price of a single 5" HDMI screen. Far…

What I'd like to see is a calculator shell that you could pop the RPi into, including physical buttons, lcd screen, battery and charger. My thinking -- most high schools require a graphing calculator, such as the TI 89 or similar, which is around $100 or so. Imagine if for that $100 you get something that can act as the same calculator, but morphs into a full computer when plugging in a keyboard/monitor? It may end up getting a lot more kids into programming that way.

If you want a screen, just buy a $50 tablet. The Raspberry Pi is basically a tablet computer chip minus the tablet.

+ GPIO pins + FOSS software + Maker community, which make all the difference.

And then you have to buy a graphing calculator anyway because no high school teacher / university professor will let you take tests with it.

Hell, I'm surprised some of my teachers let me use a graphing calculator one tests that didn't require them. They're already powerful enough to easily cheat with.

That's a pro video monitor - considerable overkill for a Pi.

Because of cheating? How can you use the Raspberry Pi (in a calculator shell) to cheat, in such a way that you can't use a ti-89 to cheat? Most cheating will be by either storing crib notes on the device (which won't do you any good in math if you don't understand the concepts), or by running a program to solve a problem for you, both of which the ti-89 is more than capable of doing -- that is its whole purpose, is to run math programs.

The ideal situation would be where the RPi foundation uses its existing clout to get a PiCalc accepted as a standard calculator in school.

For about the same price ($60) you can get this fancy little HDMI display http://www.adafruit.com/products/2260 For $20 more it comes with a touch screen. It is great for little BBB or RPi projects, zero config required for the BBB.

The price I get at the link shows $60 only if you're buying 100 at a time, it's $75 for one. Still nice to know about though.
