You don't need a lot of magnification to see with your eyes the tops, but not the bottoms, of things whose base is beyond the horizon.

The earth's curvature is very easy to see even down on the surface. It's called "the horizon".

I guess the dude never heard of his own company's iPad plans, which are ALREADY DATA ONLY

The picture at Wikipedia is of the Microwriter, not the Microwriter AgenaA. Try this page:

There's a picture on there under that name which is the device I remember -- the AgendA that is, not the Microwriter below it.

I think the poster below is correct, it's a Microwriter AgendA. The picture at Wikipedia is of some other Microwriter device. This page has a picture of the AgendA:

My friend had one around the same time I had my Psion Organizer II, ~1989 or so in highschool in the UK.

This is exactly what I do. I have 3 people who commonly misuse my gmail address, and all share my name. One is a retired Air Force colonel in Virginia, one is a real estate agent in Texas whose wife uses his email address for her clothing design business a lot, and the most recent is an Australian whose daughter has recently gone off to college and uses her dad's email address for some reason. I enjoy vicariously living part of these 3 folks lives. I have found all 3 of their real email addresses, fairly easily, and I forward their mail to them. Generally this encourages them to be more careful about not mis-entering their email addresses on web forms, etc. and in insisting on the correct spelling when giving their addresses to others, thereby reducing the future burden on me. I think all 3 of them greatly appreciate it when I do forward the mis-directed mail to them, and generally I don't twice get misdirected mail from the same source: they do fix the sender's problems for me. If the 3 of them weren't so geographically spread it might be harder -- but there are almost always clues in the email as to whether the intended recipient is in Texas, Virginia, or Australia -- or whether a teen girl, retired AF colonel, or realtor/clothing designer.

Ah crap. Me and my lazy googling. Try this one:
http://upload.wikimedia.org/wikipedia/commons/b/b6/PM5644-1920x1080.gif

It can take a 1920x1080 signal and use its scaler to render to its panel. Yes. But can any of those TVs actually properly render the thin vertical lines in a test pattern like this one:
http://www.matoverton.com/video/testcardk_1920.png
I've not seen one yet that can.
I believe that the "resolution" that they're advertising is the INPUT resolution, not the number of actual pixels on the panel.

I've put this test pattern:
http://www.matoverton.com/video/testcardk_1920.png
on every high-end LCD TV I could find near me (I have 6 around the office, 4 Samsung 6000 series 40, and 55-inch, and 2 LG 32 and 47", and not one of them can properly display beyond the 1366 horizontal resolution test lines accurately (and the 1366 lines are mis-aligned on all but one of the TVs).

Just cos you can see a dot on an i doesn't mean that it's using a full pixel to display the dot. Look at this test image on your TV, in full-screen (ie fit to the full screen):
http://www.matoverton.com/video/testcardk_1920.png
Under the solid-gray darkening rectangles, look at the vertical lines -- on the far right set of lines, are they all displayed with equal width? Those lines are 1/1920 of the width of the image. If your TV cannot display this image full-screen with those lines all being equal-width, then it is NOT 1920 pixels wide.

Let me flip that on you: find me ANY tv which has a 1920x1080 panel.

I said "TV" not "Monitor"

The *software* resolution of HD is 1920x1080. There are practically no TVs available today which have panels with more than 1366x768 pixels on them. The fact that these all advertise themselves as being "Full HD" is pretty obnoxiously misleading marketing.
