I actually have a license through work to use MS Office, but because I don't have a CD/ROM drive on my Netbook, I can't install it on there.
So instead, I went to OpenOffice for the Netbook machine. It does everything I need, but I have to agree with one of the comments above regarding the spreadsheet program. A few of my spreadsheets in excel don't translate properly. But that's just a minor problem. 
 
Can't beat the price!!!
