I was thinking of a smaller image, not on a lower screen resolutions.
Low resolution displays are quickly disappearing. On the Mac side,
the
smallest have about 1280x720 plus some (so that HDTV 720p will fit).
Free standing displays seems to be most price efficient around
1920x1080
(enough for "full" HDTV).
I live my life on a netbook with a 7" screen and maximum
resolution of 800x480. I think other people in the world also use
netbooks, but even if nobody else does, I'm going to be entirely
selfish and insist that the new website work well on my computer.
