Last week, I reviewed not one, but three new phones. You’d think that would be enough for a while, but fall is peak season for new mobile devices, and another major release — Motorola’s Droid — is upon us this week.

But before we get to today’s big review of the Droid, we need a noun.

What should we call these iPhone-like, touch screen Wi-Fi phones with music and video, real Web browsers, e-mail, sensors (light, tilt, location, proximity), and, above all, app stores? These machines can download thousands of free or cheap add-on programs — “apps” — and become GPS units, musical instruments and medical equipment.

“Smartphone” is too limited. A smartphone is a cellphone with e-mail — an old BlackBerry, a Blackjack, maybe a Treo. This new category — somewhere between cellphones and laptops, or even beyond them — deserves a name of its own.

I invited suggestions on Twitter. The best came from @mentalworkout: “app phone.” Bingo. Apps distinguish iPhonish phones from mere smartphones, so “app phones” it is.

The latest hotly anticipated app phone is the Motorola Droid, which Verizon will offer on Friday. (It’s $200 after $100 mail-in rebate, with contract. Tip: Get it at Best Buy, where you get the rebate on the spot.)

The name fits. First, it runs Google’s Android mobile operating system. In fact, it’s the first phone with Android 2.0, which offers a number of touchups and refinements.

Second, the Droid’s design screams “Star Wars,” if not “Darth Vader.” It’s jet black, all sharp angles and industrial-looking edges. Verizon asked Motorola to soften the design for better female appeal, but it’s hopeless: Droid is all masculine, all the time. When you slide the screen up to reveal the thumb keyboard, there’s no spring-assisted snap; it drags like a plow through soil. It’s all part of the manly man design concept.

Verizon is clearly taking aim at the iPhone. especially in its recent TV ads, which mock: “I don’t have a real keyboard. I don’t run simultaneous apps. I don’t have interchangeable batteries. Everything iDon’t, Droid does.”

So is it true? Is the Droid an iPhone killer?

No, but it’s certainly a killer phone. It runs on Verizon’s superior cellphone network, so it won’t drop your calls in New York City and San Francisco (as AT&T often does on the iPhone).

The Droid is just incredibly fast, so it’s a delight to use. Audio quality is superb, both on phone calls and music.

The gorgeous screen is slightly bigger than the iPhone’s; on close examination, its higher resolution (854 x 480 pixels) make text look sharper and curves smoother.

And the Droid multitasks — it can keep multiple programs open at once. Now, the usual response to this subject is: “Ooh, so you can check your calendar or e-mail while you’re on a call! You can listen to your music while surfing the Web!” True, but even the “nonmultitasking” iPhone does all that.

Still, the Droid’s multitasking pays off in two situations: when you want to listen to Internet radio while you work in other apps, and when you’re switching between programs a lot. Since they’re already open, you don’t have to wait for them to start up again with each switch.

Anyone who hates typing on glass will love that the Droid gives you a choice: on-screen keyboard or illuminated, slide-out physical keyboard. The Droid’s battery gets you through one day, just like the iPhone’s, but you can carry a spare.

Apple has always argued that a keyboard and swappable battery would make the phone too thick. Motorola points out that even with these elements, the Droid is only 1.4 millimeters thicker than the iPhone: 13.7 versus 12.3.

That’s not quite fair, though, because the iPhone’s curved case tapers in your hand; it’s 12.3 millimeters at its thickest point, so it still feels much thinner.

In addition to great speed, great audio and great cell signal, the Droid offers Android 2.0’s new navigation software. It’s as close to a suction-cup GPS unit as you can get on a cellphone, with spoken street names, color coding to indicate traffic, map icons (for parking, gas and so on), satellite view and even street photos of any address. Buy the $30 windshield bracket, which fires up the GPS automatically when you insert the Droid, and nobody will know you’re not running some $500 GPS unit.

The real mind blower/game changer? This software is free. All of it. I’m guessing there wasn’t much cheer at Garmin’s Halloween party this year.

You can also buy a $30 home dock. When you insert the Droid, an alarm-clock/weather display appears. Why not let your app phone do something useful while it’s charging? (NYT)
