From the looks of the iPad it's designed to be used primarily as a content consumption device with support for content creation. It's a good position for a first release since consumption doesn't require Apple to work out all of the kinks around how to use this brand new computing device as a way to create content. However, Apple seems to be slightly schizophrenic about the device with the release of the iWork applications for the platform. From what I've been reading the problems with using the device as a content creation platform are numerous. Most of the complaints I've read fall into one of two buckets: the device is designed as a touch screen device and input is fraught with problems, and there's no built in support for syncing work between the iPad and another machine.
Obviously Apple is aware that people aren't going to get any serious work done with a touch screen keyboard, hence the iPad Keyboard Dock and support for Bluetooth keyboards. But allowing users to hook up a keyboard to the device is only a half solution; you still need to interact physically with the device to perform some operations. John Gruber of Daring Fireball sums this up nicely in his article about the iPad:
The iPad is fundamentally a touchscreen device. You absolutely do not need a hardware keyboard for it. But if you re hoping to do any amount of serious writing with it ... you re going to want one. There are a few places in the iPad UI where I really wish the keyboard was useful but it isn t. For example, Safari location field suggestions. ... On the iPad, you must use touch to select from the list. Since you re already typing if you re entering a URL, this is just begging for arrow key support. (Ditto for suggested results from the Google search field in Safari.) The Esc key does not dismiss popovers, but that s probably OK. It s only possible to invoke popovers via touch, so it seems OK that you must dismiss them via touch as well.
As an aside, it's nice that Apple's including the Bluetooth functionality for the iPhone as well. I'm not sure how much use it will be, but it's a nice little feature that other phones won't have.
The other issue that's been brought to light is that the sync story for apps on the iPad, as well as the iPhone and iPod Touch, is really weak. Apple hasn't provided an API to allow apps to sync their data with a Mac. In fact, given that the iWork apps don't sync with the Mac I'm not even convinced that the functionality exists. Sure, you could say that since the iWork apps are smaller, lighter versions of the iWork applications for the Mac they might not want to automatically sync since there isn't feature-set parity between the two suites.
The lack of any syncing support is really surprising to me given that Apple is trying to position the iPad as a light-weight computer. The fact that it wasn't available in the initial release is forgivable but when the iPhone OS 4.0 announcement came and went without any indication of it being in the pipeline I was annoyed.
The lack of a native sync story for 3rd party apps has really turned out to be a ghetto. Each application has its own way of synchronizing data between the sattelite - the iPad, iPhone, iPod Touch - and the mothership - the Mac. Developers are forced to come up with their own way of syncing data between the two devices. Obviously this isn't a good place to be in for developers or users.
From the developer's perspective they have to either write their own custom syncing protocol or use something like WebDAV, FTP or iDisk to transfer the data to location that's accessible to both the Mac and the device. Clearly this is a waste of time on the developer's behalf and it's not even that good of a solution since it has the fatal flaw that the app can only sync data if it's running on the mobile device.
As for users: it's a complete usability nightmare. Each app has to have its syncing configured separately. The app on the mobile device has to be running for the sync to work and potentially so does the sibling application on the Mac. If either isn't running the sync will fail and user's will have to figure out why. This shouldn't be. Syncing is one of those things that users just expect to work. Period.
Synchronizing data is a common enough problem that the platform really should address it in a standard way. The fact that sync support didn't make it into iPhone OS 4.0 but iAds, an advertising API did is just appalling.
So, if you read the title of this post I think you'll know where I'm headed: Dropbox. For the un-initiated, Dropbox is a service that automatically keeps a directory on multiple machines synchronized. Best of all, for small amounts of data - up to 2GB - it's free! Dropbox could provide the infrastructure needed for mobile and desktop devices to keep their data synchronized, a great place to be. The fact that Apple's dropped the ball on such an important piece of the puzzle leaves an opening for Dropbox to become a de-facto standard for synchronizing between mobile and desktop devices.
There's only one slight problem: as of this moment there is no public API available for Dropbox. This means that even if developers want to integrate with Dropbox they can't. From what I've heard an API is in the works, but it's not ready quite yet. All I have to say is that they had better get their act together and soon before Apple comes along and eats their lunch with an integrated solution.
