I just tried on experiment on my roomate's pc. I tried accessing my iDisk from her computer. It was nearly instantaneous... switching between folders in the idisk too. On my computer (sage iMac) there is a lag of several seconds between switching folders.
What's up with this?!!?
On an ironic note, even though accessing the idisk with the pc was SUPER fast, it crashed when i tried to download something by dragging a file to the desktop...
