I respectfully disagree. According to usb.org's website, a USB 2.0 port can only supply 500mA of current. This is less current than what the Nokia-furnished AC adapter provides. If you connect something that draws more than 500mA (which is half of one ampere), the PC shows some type of error message and the port power is disabled. The port would then need to be re-enabled in some manner (or PC rebooted).

Since a USB port offers lower current, charging an IT with it is slower than with the AC adapter.
