@engrpiman: actually, I'm a big Outlook fan. I have to deal with a huge amount of email, I want my calendar and contacts right there, I want them to sync to my WinMo phone, I use folders via the wonderful SpeedFiler add-in, I use categories and flags extensively, I sync folders from SharePoint, I use a lot of rules - if you want the full range of tools for contacts, calendar and communications, (and you have Exchange to make the features work, block spam etc) Outlook is great. If you just want an email package there are lots of other tools that may indeed suit you better.
And yes, PowerPoint 2010 has the same equation editor as Word 2010; a lot more of the tools are common between the apps in this version,
