It’s funny. Comical even. A few weeks ago, I wrote that The iPhone is to Smartphones as IE6 was to Browsers. Most of the readers of that article agreed with me but almost all had a “but, but, but…” argument. This is because the iPhone is one sexy beast to users, even though AT&T can’t seem to support the iPhone, as we also noted.

This is a comical observation because my position was endorsed (if not directly) by Peter-Paul Koch who daintily comments that “[He] will shout at web developers who think that delicately inserting an iPhone up their ass is the same as mobile web development.” He goes on to slam the web development community to catering to the iPhone in the same broken-record way that web developers catered to IE6 ten years ago.

And adding insult to injury, the Guardian also picked up that story and offered their own ringing endorsement for both Peter-Paul and my perspectives.

I just got off the phone with an unnamed entrepreneur who wants to build a product that, while looking to the future and planning to diversify over a variety of products, looks at Apple’s forthcoming iPad as the launch device. I will offer you the same advice I offered him as well as the same advice I offer to iPhone only products like Gowalla.

If you want to start on the iPad, fine. You better be damn sure you’re ready to diversify quickly. I don’t care if you put it on a non-touch device like, oh I don’t know, the web with a normal browser on a normal computer… do not disenfranchise users. Peter-Paul Koch notes, in the article I linked to above, that the iPhone carries only 15% of the worldwide mobile market. Yet it gets an insane amount of attention as if it was the most important product ever created.

Newsflash… it’s not. It’s not even close.

In fact, it’s still not a business class phone (with rare exception). And in fact, developers continue to ignore other platforms… like the BlackBerry.

Sidenote: It’s okay to have a mobile web interface but don’t lose the forest through the trees. Users will feel like second-hand citizens if you don’t pay attention to their needs.

Mobile developers: Think before you develop only for the iPhone or only for the iPad. Entrepreneurs: Think before you start a company or launch a product made exclusively, or designed with a business model only for the iPhone or the iPad.
