This doesn't answer your question but:
Hypothetically, an e-ink screen like a kindle, but with a dedicated keyboard and an indiglo backlighting system that only plays interactive fiction.
Or a system that mimics the look and style of retro lcd games but can be fully detailed to play full on...
As it turns out we just voted on it, in this very thread in fact, and yes according to popular opinion the best thing that you can do with $10.00 is buy Shrek DVD's. Toilet paper was tied for second and I was the lone vote for the fancy deviled chicken.
Congrats to drenal who won the contest in an overwhelming historical landslide victory tallying a whopping 6 total votes. Remember you are obligated to buy the Shrek dvd's.
although i ended up accidentally changing my nand with no way of going back bc i didn't know you needed a gamecube controller to restore it (i have a wii minus/1.1, which doesn't have gamecube controller support)
and if i find the sd card i have my NAND backed up on, i can not only restore the NAND if i solder the right part in, but i can also put my NAND on dolphin, then i can play dolphin online, like PMEX Remix or MKWii Riibalanced
