Yes, I have.
I've found the resistive touch screens to be horrible for quick typing, the menu layouts to often be mislabeled, and simple features to be buried beneath too many sub menus.
Of course, I've only had very extensive use with a TomTom, however, I've used many others, including Navigons, Magellan, Garmin, and Sony.

The app would be much like the device, however, I'm sure input would be easier.

I suppose the biggest reason would be that I'd rather carry around my swiss army knife of electronics, rather than something from every section of Best Buy.

I like listening to my music pretty loudly. If you're not paying attention, it can be pretty easy to miss the directions, and not turn it down in time.

This has some decent features, but why no 1st Gen support? The processor isn't much slower, it runs iPhone OS 3, allowing accessory to application support, so what's the problem?

Damn. I have a 1st generation iPod touch. I was hoping to get this... Guess not.
Why not just buy a GPS for the same price? Well, why have more electronics in my car if I don't need them? Not to mention they're bulky, not loud enough to play over my radio, and many lack a good UI. The iPod/iPhone would b perfect... why neglect the 1st generation iPod Touch?

Black friday? Lame.
Engadget give-a-ways? Awesome.

Wow, this was surprising. Nice give-a-way, Engadget!

Women love to play with Wiis. We've known this for centuries.

I find this disheartening. I hope these commercials don't express Apple's true views, because if so, we could be looking at more AT&T exclusivity. I really want a Verizon iPhone...

Health issues? I'm allergic to dust! Not cigarette smoke though. I haven't seen a machine that's had a large buildup of smoke residue, so I'm ignorant to this issue. I can maybe see not wanting to repair a machine that's very dirty or smells bad. But I can't see smoke actually being worse for a computer than dust.
I wasn't thinking of the person repairing the machine, I could see that being a good reason to refuse repair.

I wonder what Mac OS features will be used as inspiration for this version.

Doesn't dust get into the machine? In what way is smoke residue worse than dust?
Seems like a cop out to me...
