Apple (NASDAQ:AAPL) won't be the first to introduce a touch-screen smartphone when the iPhone reaches store shelves on June 29.

HTC, a Taiwanese phone maker, has created the TouchFLO, which, like the iPhone, boasts a touch-sensitive display. Click here for a demo. Go ahead, I'll wait.

Notice how HTC positions the TouchFLO as if it were a piece of electronic paper to be manipulated by your digits. The iPhone offers similar browsing, but it also serves up a widescreen option that the TouchFLO lacks.

The TouchFLO is something of a lightweight compared with the iPhone in other areas, too. For example, whereas the iPhone will offer its users as many as 8 gigabytes of data-storage capacity, the TouchFLO is apparently confined to a single gig.

Still, the TouchFLO's interface strikes me as impressive enough to woo plenty of customers. Bill Gates must be smiling, because Microsoft's (NASDAQ:MSFT) Windows Mobile powers the TouchFLO, adding to a list of smartphone successes that includes Palm's (NASDAQ:PALM) Treo as well as numerous Nokia (NYSE:NOK) models.

For now, the TouchFLO is confined to the UK, where Orange is selling it to its telecom customers. Here in the States, AT&T (NYSE:T) hopes to cash in on the iPhone as the exclusive provider of that device. HTC, meanwhile, expects to begin U.S. shipments "later this year," whatever that means.

Frankly, I don't think the TouchFLO will do much to derail the iPhone when it arrives here. But I could be wrong, especially if consumers prove to be more price-sensitive than they have been in the past.

Press reports say HTC's high-end phones rarely sell for more than $400. There's no reason to believe that will change with the TouchFLO. By contrast, the low-end version of the iPhone will retail for $499.

What's more, research suggests that the iPhone will draw a limited audience upon release because of its premium price. Only 6% of respondents in a recent survey said they'd seriously consider buying the device. Not "yes, I'll definitely buy," but "maybe."

Still, that's just one survey, and AT&T says it has had more than 1 million inquiries from potential iPhone customers. To me, that says this edition of the iEverything has captivated too many imaginations for it to be derailed by a lightweight rival.

The next generation, however, could be up for grabs. For if the TouchFLO proves anything, it's this: Apple's revolutionary iPhone design isn't nearly as revolutionary as many of us, including yours truly, were led to believe.

Get ready for an iWar, Apple investors.
