[SI-LIST] Excel:an excellent tool for SI?

All Gurus,

Although Microsoft's Excel is applicable to some of SI's calculation,  but 
It's not a pratical method for recursive calculations, because it's 
running time is very long. Ofcourse, I believe you can writes own codes 
for SI analysis. As we known, lot of engineers often write Mathlab codes 
to do thier analysis. But Do you consider whether the running speed is 
comaparable to those commercial tools which dedicated to SI? Writing codes 
and writing speedy codes are different things.

Ultraeditor will replace 10,000,000 instances of a character in seconds. 
Notepad also can do same things but in hours, Wordpad in less hours, 
Winword in ten minutes.

Ray, all:

To reinforce your information, I have verified Ray's compatibility issue
with OpenOffice under both Windows XP and Linux.
