Suggestion for the 'What is a portable app' page

I thought something like the following ought to be on the page. I know it's obvious but there's mileage in spelling it out?

These are big advantages to me - not very well worded I know, but you get the idea.

And last but not least

• No setup/install in Windows required
• No multiple copies on multiple PCs to maintain
• No installs required of favourite apps when get a new PC, a new hard drive or need to reformat and reload OS
