The iPhone has been out for more than a week and the hubbub has started dying off and the realities are starting to set in. Not to try and put more fuel on the fire of hype, but I always think the point when the Reality Distortion Field effect starts wearing off* is the best time to look at the technology objectively as well as the application options available to you.

I mean, when an application that tests how long you can push a button gets web-wide coverage, you know there’s some kind of reality distortion going on.

So, I’ve compiled a list of apps from the iTunes App Store that I’ve found useful and good for productivity that you might be interested in trying out. That is, if you hadn’t already done so during the week’s excessive hype. Or if you’re not busy playing Crash Bandicoot Nitro Kart.

To find any of these apps and install them, fire up iTunes and run them through the iTunes Store search box. And if you’re favorite productivity application isn’t listed here, it could be because I haven’t tried it or didn’t like it—but then, just as likely, it might just be because of the bone-headed decision to restrict some apps by country.

* I purchased mine well before this point in time arrived.

OmniFocus

I’m bringing out the big guns first, when it comes to productivity. OmniFocus is a great GTD task management application. It’s a “port” (and I use that word loosely) from Omni Group’s popular desktop application of the same name. Though it’s on the pricier end of the available iPhone apps, the functionality offered can be accounted for.

Some developers just want to get a mobile version of their desktop application up at the App Store, but OmniFocus is one of the few that leverage the iPhone’s capabilities as distinct from the Mac with location-based task lists thanks to the iPhone’s GPS location services.

OmniFocus for the iPhone will sync and integrate with OmniFocus on the Mac if you’re running the latest version of the software. If your tasks are important to you, make sure to keep your data backed up, because I’ve read a review or two where an application crash caused complete data loss.

Mocha VNC Lite

Oh, crap. I’ve just got in bed and want to do some reading online with my laptop, to relax before going to sleep. But I’ve left a torrent running on the computer in the home office and the Internet connection is so slow, it’s almost unusable!

I’ll have to get out of bed, turn the torrent off, and if I want it done by morning, I’ll have to get out bed again when I’m done and turn it back on.

Okay, I’m sure you can think of a scenario that’s more about becoming productive and less about pandering to laziness, but Mocha VNC works like Screen Sharing on the Mac does. You can use Mocha to control your Windows, Mac or Linux computer and the level of interaction is surprisingly high. You use the multi-touch finger controls to zoom around the screen just like when you’re using MobileSafari. Best of all, it’s free.

BookShelf

BookShelf is an ebook reader for your iPhone. It does text documents all the way to Mobipocket books. I definitely think this app can boost your productivity because it allows you to get more reading done quicker. You can read any book in your entire library in the living room, on the train, heck, even when you’re pedaling away on your exercise bike. Ever tried to lug an entire library of books around? Not fun. This is simple and easy. I’ve had the iPhone 3G since Friday and I’ve already finished two-and-a-half books thanks to BookShelf.

Mobipocket, the ebook reader I’ve been using on Windows Mobile or CE devices for close to a decade, is apparently coming out for the iPhone in months to come. But BookShelf beat them to the punch and they get a vote from me.

What I’d like to see: a smoother desktop app for shoveling books onto your phone and a revision of the “chunking” process that turns it into a background function you don’t need to worry about.

Evernote

I can barely live without Evernote on the Mac these days. The iPhone version makes it easier to create notes on the go and also easy to view them, but if you want to edit them, you won’t be too happy—Evernote doesn’t allow it. I’m hoping, nay, begging, that they’ll build the ability to edit existing notes into a future version. Please, guys?

You can do snapshot notes with the iPhone’s camera or audio notes. And, of course, you get searchable images as usual once your snapshot has uploaded to the Evernote server.

NetNewsWire

I’m a user of NetNewsWire on the Mac, so this app had me excited. Unfortunately, it’s not quite the experience I had hoped for, and not only that, but it won’t seem to download my entire collection of feeds as synced with Newsgator.

But, where before I spent precious office time catching up on feeds (after I got my real work done, of course), I can now get (most of) them done when I have an idle moment—like when I’m waiting for someone to say something interesting at that dinner party! This frees up extra time to work on new projects or take on another small client project back at the office.

Sidenote: before you lambast me for my previous habit of reading feeds when I could’ve been working on a new client, feed reading is actually an important task for a writer whose work is primarily online. It’s not extra time I was desperate to have before, but thirty minutes a day can add up.

Google Mobile

There may be no Spotlight on the iPhone (yet, the optimist would add), but Google Mobile does the job just as well as a Mobile Spotlight would. That is, aside from the system-wide integration that it obviously lacks.

Google Mobile will let you perform a search that hunts through your contacts and the web and provides you with the most relevant and local results first. Does the job damn well, while we’re waiting on Spotlight. You hear that, Apple? We want it along with copy and paste, okay?

Twinkle

You might be surprised to find a Twitter client in a list of productivity apps, but there’s a good reason for it. Since I’ve installed Twinkle, I’ve stopped using Twhirl or constantly refreshing the tab I have Twitter open in; I know Twinkle will let me know when someone replies to or messages me and since installing it my time spent on the site in general has decreased a lot—without really affecting my participation in the community there.
