I've written about the Microsoft Live product line before. Live Writer is one of my favorite on/offline-friendly tools. Now Live Mail comes along. It's still beta (but hey, Gmail has been beta for what...3 years?) but looks very promising.
My wife runs her business from her Hotmail account (I know, I know...it's on the list). She's traveling for a conference soon and wanted a way to plow through some of her mountain of emails while on the plane using her new Insprion 1525 Vista laptop. However, we've yet to pull the trigger on Office 2007.
Worst case, I figured she could leverage Outlook Express but I ran across a post referencing offline mail options. #2 on the list was Live Mail. Super. I'm loading it now and will report back.
...good grief Live products take forever to load...
