FireWire instead of USB 2.0 in Windows XP
After Microsoft has already rejected Bluetooth, Windows XP will probably also be delivered without support for USB 2.0. Instead of the 480MBit/s fast USB 2.0, Microsoft is now relying fully on the 80MBit/s slower IEEE 1394 (FireWire) standard.
This seems paradoxical, since FireWire was developed by Apple. Microsoft justifies this decision with the fact that both Bluetooth and USB 2.0 are not yet fully developed.
This step will mean a major setback for these two emerging standards, since other companies will probably also support them without support from Redmond especially for USB 2.0.
