I think the PAL standard is 576 lines. The digital SDTV standard is 
640x480, the same vertical resolution as the NTSC standard (wikipedia is 
telling me all this). The 1080p image is therefore 3 times wider, but 
only 2.5 times taller because of the different aspect ratio. I guess 
that's 7.5 times the area.

If the images you saw were mountains and lakes and so forth then they 
probably weren't showing off the picture properly. You often see CG 
movies like Ice Age used as demos in shops because the picture is much 
sharper than a corresponding live-action movie (one of the many reasons 
CG stands out so much).

I think the difference is a bit like upgrading to power-assisted 
steering from an older car to a newer car. At first you think "well, 
yes, it's a bit easier, but non-power steering is hardly that 
difficult", and then if you ever go back to driving an older car you 
think "bloody hell this is hard work".
