One of the common rhetorical questions laid about before me was whether I actually use all the applications on my smartphone. This is a fair question, and the answer remains that it indeed comes down to a handful of applications I can honestly categorize under frequent usage.
The Desktop Analogy and Occasional Use
But that's the thing - frequency of use. Users like myself like to treat their smartphones more as portable computers than just powerful phones. That is, people like me want all the occasional-use applications on the phone, just in case. It would be analogous to the myriad of applications installed on a Windows, Mac, or Linux desktop environment. I may not burn DVDs or CDs on a daily basis, but I'm not going to reinstall Nero Burning ROM every other month for each time I need to burn an optical disc. Likewise, I'm not going to reinstall an ATM Hunter app or Starmap app every time I occasionally need it.The last thing a user wants to do the moment a task needs to be done is to install and configure settings. (In general, desktop software and mobile apps lose some or all customizations and data upon removal.) Essentially, it's all about the convenience of having the tools and resources you need available to you, even if you only use them once in a while.
It can seem overwhelming to an observer seeing a user swipe across eight or nine screens of apps on an iPhone, and it's certainly valid that it can look like a random mess. It requires relying on memory of where a particular app sits (turns out to be easy for the primary user, but slower for guest users), as well as reorganization of their icon order on the pages. For example, there seems to be this trend of people sorting by a gradient of usage frequency, with the most used apps on the home screen, and gradually sorted towards the least used apps on the last screens.
Search versus Browse, and Low-Use Applications
In the case of this phone, there's no function to sort all apps by name or any attribute, but the default behavior is that any new app gets placed at the end, or in the first gap on a screen's icon grid. That effectively sorts by last added. If you're installing all applications in a huge batch, such as if syncing for the very first time with apps all sync-ready in iTunes, then they install in alphabetical order by name. Beyond that though, it's all manual sorting.So when version 3.0 released with its Spotlight global search feature and removal of the cap on number of apps, the iPhone OS seemed to step closer to this desktop computing behavior. The search versus browse mentality is very much like the live global search on a desktop platform, such as with Spotlight on the OS X menu bar and Windows Search in the Windows Vista/7 taskbar. You still browse for applications (and anything else from emails to calendar events), but for anything further out of reach, such as low-usage applications, the search part of the hybrid system comes in handy.


Linear Browsing versus Planar Browsing
It's also worth noting that another suggestion I've come across is to allow vertical swipes for vertical pages/screens, whereas the iPhone OS maintains a horizontal row of pages that only move left and right, with dot indicators at the bottom to show the current position. This is a linear approach. It has its cons, but it's arguably easier to keep track. Typically, most other phones offer a single tall vertical page with scrolling for all applications, and movement is also linear, with the scrollbar being the indicator of position.The Palm Pre takes a different approach with a grid of screens of icon grids. This could potentially mean less swipes when browsing, provided the user can keep track of position. There are stick indicators showing where you are on the grid. This remotely like organizing by workspaces in Linux or Spaces in OS X, and its only limit is how much the user can remember about the position of a specific app in a cartesian plane instead of a linear. The question then becomes what the threshold is for how much we can handle - 2x2, 3x3, 4x4? Will a user remember that the Pandora app was on the Marsha part of the Brady Bunch grid? Or was it the Cindy part of the grid? We risk confusion, but it's an expense for the gain of quicker movement on a 2D plane. In some ways, this kind of planar browsing is much like that of desktop computing, except with a much more limited screen size to do it, so we'll see how that plays out.
