About iOS5 On The iPod Touch 4G

Once installed on here, I may just store a lot of stuff on iCloud, which will free up space on this machine.
Another thing-updates to system will come over the air & not require me to attach this device to a main computer. Instead, this will be a completely independent machine. There will be no need to have a main box. After all, the iPhone, iPod Touch & iPad can function as computers. One need not have a desktop or Notebook to be functional.
The world is going portable-no need to lug a laptop with you. Think of all that extra weight being saved.
