Im considering new hardware and now I see some things are USB 2.0, whats that?
USB 2.0 is the new standard for USB devices. None of the computers as of the first part of 2002 have USB 2.0 support built in. The only way to get USB 2.0 support is to have an add-in card to plug the devices in. The advantage to USB 2.0 is devices will be able to communicate with the computer 24 times faster than the present USB devices do. The computers themselves are mostly USB 2.0 now. This speeds up transferring pictures, scanning, writing to external drives, and probably printing, etc.
