Firstly, thank you for taking the time to reply. In your opinion, specifically regarding the hardware, do you believe there are improvements that could be made (in terms of design)? > What you've described is nearly exactly the design of the > OLPC.

Kind of, but it has speakers, daughter extension boards, swivel display, custom "motherboard" PCB, etc. I do appreciate that it was a different time though and I have the arm chair privilege of looking at this through a modern lens. > The charging circuitry will charge the battery if given > anywhere between 11 and 18 volts (there are user reports > of slowly charging with 9V), and will not be damaged if > exposed to higher, or negative, voltage.

Supporting AC wouldn't be incredibly difficult either (many phone wall changes are quite small), but of course would increase size and/or complexity. Also I think it's good to keep kids away from high voltage/current AC. > The OLPC XO-1 is quite easy to disassemble and repair.

It's certainly much better than I thought in terms of repair-ability, but I still believe it's overly complex. The display for example should get a display signal via a HDMI cable (which is shielded) and send the touchscreen data via USB, as well as providing power for the display. If the cable breaks, sourcing a replacement is relatively easy given the standardization. If the display breaks, an external one may be used. > People took advantage of the easy-to-disassemble and > thoroughly-documented hardware to develop community hacks. > A popular one was to replace the membrane keyboard with a > particular USB keyboard, which could be cut up to fit the > chassis, and internally wired to one of the USB ports. > I've seen a tutorial on how to solder an extra 256 MB of > memory in. That's awesome, but it should have come with an off-the-shelf drop-in removable USB keyboard anyway. The keyboard should be a valuable item, even if the rest of the laptop is completely destroyed. > The G1G1 laptops came with a preinstalled collection[3] of > educational material, mostly from Wikipedia.

The school server I highly doubt would have worked correctly in many cases as it relies on too much to work correctly (server setup correctly, networking, stable electricity supply, etc). These days I would make all the books stand-alone, probably distributed as markdown as you can read them raw or compile them into some more pleasing format. I think requiring some non-standard program to open .xol files was probably a move in the wrong direction.
