Pathfinder is free, too, and has a lot more material in its SRD. Is there that much application support for 3.5 that Pathfinder doesn't have?
That was going to be my point too. The SRD exists, but then as now, it is only the Core and a few other books, most of 3.5 content is not on the SRD, whereas everything PF by Paizo, and many 3PP PF rules are a part of the free d20pfsrd. Back when I was playing 3.5, I hardly ever looked at the SRD. And now despite having most of Paizo's books in PDF form at least, and many 3PP PDFs, I use d20pfsrd.com every week as my primary tool for game prep. If I have a PF question, I generally don't look at my PDFs rather I go online at d20pfsrd.com. This also means that PF gamers who have access to the internet, reasonably don't need to purchase anything from Paizo in order to play Pathfinder - the rules are entirely and freely assessable.
