Firefox and OpenOffice can both be downloaded. Unless you are going to be doing major word processing/spreadsheet work on your netbook you probably don't need MS Office. I've determeined I don't need MS Office at all and have been happily using Open Office for a couple years now. It can read/save MS format, so no worries (although it sometimes messes up my bullets in Word format).

If you need something loaded from CD/DVD and have a second computer, you could always network them together and share the optical drive for the installation.
