Yep, I dislike sitting within 3 feet/1m of a 24" monitor and within 6 feet of a 48" screen.

So first, let me say I didn't really believe that chart at all initially. So I looked into it, and I figured under what principle it is based; and I must say, while it is not fundamentally flawed, there are several points that make it seem very imprecise to me.
First of all, it assumes 20/20 vision. But a quick Google tells me reality is quite different:
http://www.isd.mel.nist.gov/US&R_Robot_Standards/Visual_Acuity_Standards_1.pdf said:
It turns out that 20/20 is not perfect human vision. Indeed, it is near the average for adults in their 60’s as vision degrades. Good vision in young adults with no visual impairment is generally between 20/16 and 20/12, much better than 20/20. 20/20 vision has come to be interpreted as the limit Figure 1: Snellen Eye Chart of “normal” vision with which an individual can cope well enough in school or industry and hence does not require correction. Vision beyond 20/20 is generally improved with corrective lenses.
Secondly, what is being measured in no way tells you everything you could possibly want to know about human vision:
http://en.wikipedia.org/wiki/Visual_acuity said:
20/20 is the visual acuity needed to discriminate two points separated by 1 arc minute—about 1/16 of an inch at 20 feet. This is because a 20/20 letter, E for example, has three limbs and two spaces in between them, giving 5 different detailed areas. The ability to resolve this therefore requires 1/5 of the letter's total arc, which in this case would be 1 minute.
Being able to discern points is not all there is to it when it comes to perceived image quality. My guess is that this is most likely to be determined primarily by horizontal cells - and even in the fovea, things aren't quite as simple as a 1:1 mapping. For example:

The clusters of terminals contact cones in the same manner as the HI cell terminals and because of their bigger field size contact more cone pedicles (9-12 in foveal retina, 20-25 in peripheral retina).
Finally, consider that video compression will never be perfect, and if a decoder only supports 720p then chances are it doesn't support anywhere near as high a bitrate as most 1080p decoders (Tegra does supports 14Mbps in 720p and 20Mbps in 1080p though, FWIW). So in practice, considering only whether you can see every single individual pixel doesn't seem like the right approach to me, unless you played a 1440p 100Mbps clip on a 720p screen or something like that...
I'm not saying there are massive benefits to 1080p beyond the screen distances in that chart. But saying you can't even detect 'some of the benefits' when further away than that is completely insane in my mind...
It seems to me a lot of people mistake this aliasing for "sharpness and detail". ARGH.
Hah - people ftw?
The myths about image quality can be depressing at times...
I was an ardent Psion 3/3c/3mx user back in the day:
Wow, that's pretty cool!
These newest gadgets are certainly amazing - if I wasn't such a born-again-luddite when it comes to gadgets I'd want one (my mobile phone doesn't even have a calculator function
).
Hehe, I can't blame you. I don't think I ever used a 3G phone (i.e. actually used the controls etc.) before I went to MWC last week; I really love my iPod Touch though. In fact, given how subpar most of these phones are, I think I'll stick to that for some more time
(LG's Arena was nice though, it's funny that the most impressive phone at the show wasn't even a smartphone...)
WRT Netbooks, for my uses I don't think it'd be a big deal that it's not Windows as long as web browsing speed is great, Flash is supported, and Google Docs works. I used a 12" ultraportable for a pretty long time, and honestly I barely ever used it for anything I couldn't do on ARM. Of course, I'm sure for some people it's the exact opposite but then again I truly wonder how many of those ever used ultraportables or netbooks rather than much bigger laptops.
