I also PM'd Neal about it just the other day but I know he's been busy.
Originally it was on my HTC Hero, which was not too bad as I could use the little trackball to navigate around the screen to avoid clicking the ad. Now I've just got Galaxy S2 and there's no trackball so the only option is to touch the screen, it's pot luck if I go to Amazon or not, but it is very frustrating.
And I've used the default browser, dolphin HD (and mini), and Opera - all with the same result. The hyperlink for the Amazon download store just extends all the way down the page.
Edit - dammit, beaten by AVGWarhawk - I spent too long searching for that thread!
