Ah, a Radio Shack aficionado, I presume.
I was one of those 80s kids who grew up with

I was Z80 and M6809. The rivalries back then were serious business. ;-)
But it seems like the price threshold is no longer a problem. Maybe
what we need is a completely hackable convergence device that you can
plug into any commodity TV, keyboard, and thumb drive and go. No need
to build a radio into it. Let that be an optional external peripheral.
That would be a Raspberry Pi. SD card rather than thumb drive, but...$75
(I mean, I have a $9-many-years-ago thing that ran Linux, so it could be
cheaper, certainly, but a fairly fast ARM with several GB of memory is $75)
gets you...plug in the sd card, keyboard, mouse, and HDMI (newer Pis
require a Micro-HDMI to HDMI adapter, which is like another $5 or $10), and
you've got a fully functional Linux machine. One would think that it
wouldn't be too hard to build an OLPC-like environment for it (it probably
already exists).
I'm amazed at how ubiquitous Pis are in the control system for the
telescope I work on, but maybe I shouldn't be. After all: it's $75 for a
general-purpose Linux box with a bunch of GPIO pins to play with. That's a
lot cheaper than designing a custom hardware anything.
