Yeah, not an easy issue. There are some tools that sort of help, but none that are really great, except the iPhone/iPad simulator (as part of the Apple developer kit if you’re on a Mac) and perhaps the Android Developer Kit.
For the most part, I just cross my fingers and hope for the best. With all these devices, I figure the pressure is on the manufacturers to get it right, as people will turn away from their devices if their rendering of web pages is lousy.
That’s the impression I get, and lots are running on Android, I believe, which seems pretty good. As for Windows Mobile, I don’t know much about it, but I assume (because of its name alone) that it’s a mess. :eyebrow:
