For most users the highlights are: lists and better statistical packages.
With chart data in a list, the chart is dynamically updated when new data is
added to the list. The stat functions now give meaningful results with large
numbers (e.g. STDEV of 100000001,100000002,100000003). There is a Research
Pane or Pain depending on your point of view.
Then there is XML support, Smart Docs and Person Name Smart Tags - of no use
to me but vital to some.
