In reply to myth:
card reader all the way
1) it'll be faster if you buy a decent card reader... Lexar or sandisk
2) you don't risk damaging the USB connector on your camera
3) you can use a different card in the camera and carry on shooting
until you get one though try this
open the cameras fodler as you currently do
grab the first 20 files and copy them to the folder on your PC you want to store them. wait until that copy has finished, grab the next 20. repeat until they've all copied
but get a decent card reader would still be my suggestion
