No, you have some issues that need fixing!

I'm a big fan of Nike + and their Nike + GPS iPhone app is quite impressive for something that costs $1.99. Not having HTML5 compliant site is their prerogative (though I hope one is in the works!), but they should have at least detected that I was on an iPad and served a more appropriate message and CTA (call to action), like a link to iTunes to learn more about their mobile app.
