It should be considered HD, as for example older CRT or Plasma based HDTVs are 1024x768.

Officially: "720 vertical lines in widescreen ratio" is considered HD resolution.

I can't believe I'm interjecting here

But 1024x768 isn't a widescreen ratio

Actually, widescreen refers to the ratio of physical image dimensions, not of their x/y resolutions (i.e. pixels can not be physically square). In the case of digital signals and square pixels (most newer TVs and monitors) obviously the two ratios match. Think that the term "widescreen" originates on analog supports, where there's no notion of pixels.

Anyway, yes, 720p is rendered on older plasmas on panels that are natively 1024x768 with pixels physically elongated in a 4:3 ratio and is still considered HD according to some specifications.
