Well, yeah. I removed a couple of interesting, but unnecessary links this afternoon (to the Phillies site and PhuturePhillies), because on the iPad (or presumably, any similar-size touch screen that doesn't represent as "mobile" - e.g., phone), they were over-running other elements that are necessary.
Further, the actual colors will render differently on different devices - and on different displays even if connected to the same device. (Have you ever attempted to get exactly the same color balance on two monitors attached to a single PC? Unless the two monitors are the same manufacturer and model, it's a challenge - and even then, can be.)
My concern now is solely with situations where things aren't working properly. What andyb reported (I think), that I subsequently saw on the touch screen, was a situation where an element that's supposed to suppressed on touch screens (for reasons that have to do with scrolling behavior) was not, in fact, suppressed - because I made a labeling mistake in linking the CSS to the HTML (don't worry if that's Greek to you - just read it as "I made a mistake..."). I think it's fixed now - but I don't know for sure, and can only continue to improve it if I get feedback indicating continuing problems.
As for only seeing a portion of the header graphic - that's deliberate, actually. I made the thing wide enough that (I hope) the vast majority of users won't have screens so wide that the header "falls short." The price of doing that is that users with narrower displays will only see part of the image. You can always scroll across if you really need to see Maikel and Freddy/Cesar. As it happens, I usually run in a window that only shows five pics (Rhys through Odubel), even though that's not the full width of my monitor. I don't see much reason to widen the window beyond that - but I expanded the header, because I know that some users will just run in a full-screen window.
