Has anybody else noticed that a significant chunk of space seems to be taken up by the new 4.0 upgrade? Back when I had 3.1.3, I seem to recall that I had around 7.4GB of available space on my 8GB iPod touch 2G. After updating, it reduced the available space to 6.84GB. I'm sure that the new OS is pretty hefty, but it doesn't really seem like it would take up an entire gigabyte of space... I'm sure there's some underlying reason behind it all, but I was just curious to see if anybody else had noticed this. I've attached a screenshot of the free space indicator.
