“Is it a phone? Is it a tablet? An iPad killer? Or what?” These are the questions that stood out to me in much of the online commentary about the Dell Streak, the new mobile device launched by Dell a few months ago. And many people answer such questions by describing it as a smartphone.

Thanks to my friends at Dell, I have a Dell Streak which I’ve been discovering a little this weekend.

If you want to record audio and post your recording to the web, all without anything other than your iPhone or a web browser, it’s never been easier to do that than now.

You’re spoiled for choice with a growing number of web services and iPhone apps, all (currently) free.

I said that a few weeks ago: iPhone is all about the apps and I’m more convinced of that than ever.

As I was scanning the Wall Street Journal on my iPhone, I got to thinking about some of the other apps I have installed on this mobile device.

If you have an iPhone, I advise you to visit the iTunes App Store immediately and install Animoto, a free app and one of the coolest I’ve yet seen for iPhone.

Over the past few years, I’ve had great enjoyment from a wide range of devices – ones I’ve either purchased myself or which have been given or loaned to me by companies via their PR agencies – which I’ve written posts or produced video reviews about, recently over on Next, my tech blog.

The latest device I have for such a purpose is an iPhone 3G which arrived by courier late on Friday evening, thus giving me much of the weekend to get to know it a bit.

One of the communication technologies I like experimenting with is video.

That’s why I play with new tools like Qik (live video streaming from a Nokia mobile phone) and seesmic (video conversations via your webcam).

I discovered another one today that I find so compelling that I’m just amazed the whole internet isn’t a-buzz about it (although there is indeed plenty of buzz).

This is Animoto, a web-based service that automatically creates a video from images and music.

That rather dry description does this service little justice. You have to see what it can do to fully appreciate its potential.

Take a look at this:
