. It is my . It is lighter, thinner, smaller, and faster (for at least some tasks) than my notebook, yet still allows me to do virtually everything I might need .

It's not perfect, though. Here are five things that I feel the iPad needs to be complete and to truly enable me to be productive anywhere and anytime.

1. File Management. The iPad--whether you choose the 16Gb, 32Gb, or 64Gb model--has a finite amount of memory to work with. There is no way to upgrade or expand the storage capacity of the device, so it makes sense that you don't really want to store files on the iPad. Storing data on the device itself also makes it a greater risk should it be lost or stolen.

Fair enough. It's a mobile platform in a cloud-driven world and I can store my files on Box.net, or iWork.com, or Google Docs, or a Windows Live SkyDrive, etc. There are plenty of free or low-cost options for storing data on the Internet.

However, the iPad doesn't even make accessing those files simple or intuitive. I can view a file in Box.net, but in order to or Numbers I have to e-mail it to myself, open the file attachment, then tap the button at the top right of the display to open the file in the appropriate app.
