A lot of users that have 15" monitors can only support 640x480 resolution.
Even if they can support a higher resolution, chances are that it's either
too small to read, or the user doesn't know about changing resolutions.
Forget formatting the text, that's not the only problem. The main problem is
going to be the width of the page itself. For a 15" monitor, that's probably
going to mean your page must be about 536 pixels wide. That's not much at
all. Basically, that's the same as the page being as wide as a little less
than putting two copies of your rc chopper photo that's on the front page
next to eachother.
I would say that any web site that these users go to will have this problem.
Most users who are on the web are using at least 800x600 resolution and more
moving to 1024x768 with each computer shipped. You may want to drop your
monitor down to a lower resolution to get a better idea at how your page is
viewed by those users.
Basically though, if these users represent only a small portion of your
viewing audience, then it's not worth the time and expense to support them.
These users should be used to this issue though simply because 99.99% of web
sites are designed for resolutions higher than theirs.
Hope this helps,
