I tried opening some of my 2003 spreadsheets with 3D graphs in Excel 2007 and
the performance is painfully slow. The graph colors changed and it lost the
feature where I could rotate the graph on it's edges and view the 3D graph
from many angles.

Also, everytime I make the slightest change the redrawing takes almost 30
secs to a minute. I have a decent machine 1.7GHz, 1GB RAM WinXP Pro SP2 and
the program performance should be better than what it is now. I know that
this is a beta software but I thought I still need to point it out.
