I concur.
IMHO, it is usually far better to upload
the images to the computer then view them
there than viewing the images and selecting
them while they are on the camera, connected
to a USB cable.  In fact, I would further recommend
that you use a card reader to transfer the images
to the computer.   While the software from the camera
manufacturers work fine most of the time, I have had
problems with every one them under odd circumstances,
sometimes resulting to loss of images.  I have used 
Canon (by the far the most), Nikon, Olympus, Kodak,
Sony, software.   "Odd circumtances" could be loss
of physical contact during image transfer, lose/faulty
USB cable, spurious problem on your computer OS, 
version of drivers not fully tested with your particular
version of camera manufacturers.
