Good question!

• File storage above all, with files and documents accessible from anywhere.
• Collaboration would be a plus but I'm not sure if things are that advanced yet; they've only just discovered the ability to share documents on Google.
• Email is handled through the web hosting company (which we're not entirely thrilled with, either, but that's another issue, I think).

Thank you for asking. As I said, there are no real techies involved (including me), so it's hard to even know what questions to ask and what details are important.
