I got a new PNY 8gb usb stick so I downloaded the standard version, installed it, and launched it. When it came up at the bottom it said "7.2GB free of 7GB". I suspect maybe its rounding down to 7 because right-clicking and selecting properties for the usb drive it says 7.45gb total. This was a virgin stick and all I installed was the Portable Apps Standard edition. I have a screen shot if you need it.
