Iconfactory recently showed of Twitterrific for the iPhone and it’s currently available on the Mac. What if there were the possibility that for $20, you could get both applications ad-free? That would be a hit because you’d essentially get the iPhone app for $5. You could then synchronize the settings on one to be on the other. If you’re on the go and don’t like how your iPhone displays the tweets, change it on the fly and the changes will automatically adapt to your Mac.

Another possibility in my mind would be the marvelous blogging app, MarsEdit. If Red Sweater Software were to release an iPhone application, you could easily write articles on the go. In the car and have a random thought? Just grab your iPhone or iPod touch. If you have connectivity (whether it be GPRS, EDGE, HSDPA, or WiFi), you can instantly post to your blog. Perhaps your in a keynote conference and you want to do a live-blog? This could be an excellent way of blogging instead of having to lug around your laptop.

A final idea would be the oh-so-interesting game, Spore. This may very well be planned out, but if you could sync your creatures and worlds between your iPhone and Mac, you could very well have the next Nintendo DS or Tamogachi on your hands. Continuing your virtual evolution with your creature on the go could be very addictive and cause more people to run into streetlights. While it’s not a possibility yet, if the iPhone/iPod touch were able to create an ad-hoc network over WiFi, your characters could roam around to other Spore Mobile users’ worlds and others come into your worlds. The possibility is there, the technology just needs to be put in place.

The App Store is a very cool thing that will definitely be big and something to follow once it’s released. Let’s just hope that developers play their cards right.

Firstly, I can access the web from virtually anywhere. Now, obviously saying that I can access it anywhere would be false, because there isn’t an open Wi-Fi network regardless of where you are. But, I’m fortunate enough to almost always be near a free wireless connection, which allows me to reach into my pocket to check my email, read feeds, get movie times, or do pretty much anything without having to yank out my laptop and spend a few extra minutes firing it up and shutting it down. Convenience is key, and I find myself having extra time for working and socializing when I don’t have to waste time fiddling with gadgets that I really don’t need. The iPod is quick and simple; even if it saves me only a few minutes every day, those are a few minutes that didn’t go to waste.

Secondly, its calendar is much more handy and accessible than my mobile phone’s. I’m a Windows user by circumstance, so my enV on Verizon is not the most convenient device in the world if I’m in need of accessing dates and events online or on my laptop. Instead, I use the iPod touch. Most people are bound to say, “Why on Earth would you need a calendar on your iPod?” but they obviously don’t own an iPod touch. Syncing with Outlook is a snap—especially since the calendar function is the only feature of Outlook that I use—and syncing Outlook with Google Calendar is just as easy, thanks to Google’s program. Not having to carry around a giant agenda with me at all times is an experience that I’d never like to go through again, especially when I’ve got an absurd number of due dates and appointments to keep track of. The two devices that no one will ever catch me without are my mobile phone and iPod, so why wouldn’t it be perfectly natural to both have a calendar feature?

So, aside from the gorgeous interface and obvious thinness of it, these are my two main reasons for paying $399 plus tax—a fortune for many people— for a 16GB device… excluding, of course, the really fantastic people that I meet based on conversations that start with, “Oh my gosh… that’s really pretty. Is that one of those iPods?”
