I agree with you here
Many of the apps I dont use from the list. I watch dvd's on my dvd player, not my comp. I dont play with graphics much, so dont need photo editing.
For me, the more essentials would be
Antivirus
AntiSpyware
Firewall
Recovery/Boot disk
Alternate Browser
Office App
cd/dvd burning sw
Outlook (mail client, Outlook prefered)
