In response to: Windows 7 and Office 2010 sparklers :-)
I am not sure what Randall Kennedy is talking about, but I have Office 2010 loaded on my 4 year old laptop, and it is amazingly fast. Faster than Office 2007.
And Microsoft has put in a "lot" thinking in the UI and UX for Office 2010. Edward Tuft's Sparklines and Slicer in Excel 2010, among many other, are amazing features. I would say Office 2010 is at least 2 years ahead of its competition. I personally prefer Linux and have been a Linux user for 10+ years, but I like to give credit where it is due.
Licensing aside, Microsoft did an amazing job, and we should compliment them on a job well done.
