New Computer!

After eight years of nursing my old Dell with Windows XP through increasing numbers of frustrating -- and, to me, inexplicable and irreversible -- problems, I finally broke down and got a whole new desktop system with a Windows 7 OS. The biggest challenges I'm facing right now are getting used to this keyboard (especially the space bar), dealing with my Word 2003 docs vis a vis Word 2010 (and just getting used to 2010!) and restoring my old favorites list.

So if any of you have suggestions or tips, bring 'em on. I'd be most grateful. :)
