Windows 7 - Selling points for Windows 7

So we are starting to migrate over to Windows 7 from XP in the workplace and doing so by an opt-in basis. After a while we will start pushing it slowly.

I want to hear what you think the selling points of Windows 7 are so it will be a seamless experience and increase productivity for the end user. The main activities people do in our office is run web applications (in-house built), work with Acrobat/InDesign/Word/Excel/PowerPoint, email with Groupwise, scan to PDF (desktop or email), print, copy, give presentations (projector) and sometimes view video conferences / presentations.

What I believe are key features coming from XP to 7 (order of importance):

1.) Search programs/files from Start Menu and specific search in Windows Explorer. Our file server is indexed so it should be responsive.
2.) Snapping windows to the top of the screen maximizes it and click-dragging it down restores it. Aero snap will help on single-monitor setups to view two documents / web pages side-by-side. This feature does not seem to work with multi-monitor (at least I don't think)
3.) Pinning documents to applications in the taskbar for frequently used documents. This works for documents on mapped networked drives also.
4.) Fully function and new UI calculator. Maybe people will stop using their calculator on their desk (probably not).

One thing I would like to change is the program that works to scan PDFs from Sharp scanners. I would like to remote the program (Sharpdesk) from the image since it has a bunch of networking problems and just use Windows 7 built in Fax and Scan. Is there any way to do this?

Can you guys think of anything else?
