That's not really a limit of mobile devices, but rather a result of
bad webdesign.

Because Eyeglasses with displays completely take away your ability to
react to your surroundings and are totally unfit to be used for _any_
kind of mobile device usage.
They are meant for your sofa. Using them elsewhere is dangerous to you
and others.

This are not facts, this is a marketing text snippet.

Getting rid of a display and introducing eyewear you can't really use
anywhere but at home doesn't seem like that huge business-opportunity
to me.

You should buy one, because you should be able to use it.
GTA04 has video composite output via the 2.5mm jack, which is
supported by the OMAP processor. I don't know if anyone has tested
this yet, but it should work and the eyewear you mentioned offers an
iPod adapter which could be easily made fit with an 3.5mm to 2.5mm
adapter or by replacing the plug manually.

These things have a ton of problems. a) they use a lot of space b)
they cost a lot c) they use a lot of power d) they can only be used on
plain surfaces. So again, this is not fit for mobile usage, but for
portable usage only.

Digital pens can be very useful, but I don't see their purpose for any
mobile handheld device usage. However, as GTA04 is a standard linux
device, any such pen which works on any linux machine can be used. If
it has USB or bluetooth and a driver is available, it can be used.
