Sure, you could possible pair down iTunes for installation.
My company (having a globally installed base of 35,000+ workstations) will install and support BB software on a specific employee’s assigned desktop/laptop and is willing to do the same for iTunes to support the iPhone.
Our mobile phone users don’t create content on their phones. The BBs and such are generally only used for voice, email, calendars, notes, contacts.
Because of the way these devices are used, we're not required to install and support BB software on every workstation through-out the enterprise that a BB user may come into contact with throughout their business day.
However, the iPad is much more that a Black Berry/Smart Phone/iPhone.
Our employees that are asking for iPads are looking to eliminate the need to carry a laptop to access Intranet web sites, deliver presentations, check and compose email, create simple documents (Word, Excel, PowerPoint compatible).
Any content that is created on the iPad needs to be accessible and shareable via USB and not just over 3G and WiFi. The vast majority of our global operation does not have WiFi coverage (and won’t anytime in the near future). 3G coverage is not always available or may be spotty (many locations only have the Edge network available and or no cell coverage due to the buildings structure).
As such, the inability to mount the iPad as a USB storage device to share content without iTunes severely restricts the device.
Apple, yourself and others chime in and say just install iTunes.
There is a very significant cost in deploying, supporting and maintaining iTunes on all of the workstations that iPad users may (or may not) need to connect to across a large enterprise - security, lifecycle, and deployment planning; QA and Certification the current and future application versions on each of the various workstation models (images) and environments (physical & virtual); deploy the application (tech and push installs); etc.
Is Apple, you or they going to pay for all of this this?
Quite frankly, there is no valid technical reason that the iPad cannot be plugged in and mounted as a generic USB flash drive to enable the sharing or files (other than Apples possible business desire to force us to us iTunes).
Until this is corrected and broad support for SSL VPN is available, we will not seriously consider the iPad for anything but very small well defined installations having a limited business scope.
