I got a new PC earlier this week (more on that later) but I was copying a 3.5GB file from my server. This is how long it said it would take:
I knew the network stack wasn't that great, but Vista, you're killing me...
The irony was that I was trying to copy my XP backup to burn to disc and wipe Vista off. I think its 'Spidey Sense' was tingling and was trying to forgo its doom.
