Poll: Which office software suite have you chosen?

Microsoft plans to release Office 2010 to manufacturing next month, with availability to business customers in May and in retail channels in June. (Full disclosure: I'm currently working on Office 2010 Inside Out, to be published this summer by Microsoft Press and distributed by O'Reilly Media.)

I've put together a poll to help me determine how I cover the product, and specifically which alternative products I use for comparison purposes.

If you've made your choice for a specific reason, please feel free to leave details in the Talkback section. Also, I'm interested in feedback from anyone who is currently using the Office 2010 betas. Likes? Dislikes? Based on your experience, will you upgrade to the final version when it's released?
