- XP is now obsolete. Get ready to purchase more software.
- Your applications that ran on the 32 bit platform might run but don't count on it. You'll be pressured to purchase the "NEW" 64 bit Office application.
- Better support for antivirus and antispam (you'll probably have to purchase this as well).
All in all, more blinky lights and better performance will make this a much more robust OS but everything comes at a price.
