When I use someone else's computer - it annoys me that they do not all have my favourite apps installed on them.
Well there's a great way of taking them all with me.
It is called PortableApps and it is basically a suite of free programs which, instead of installing to your computer's hard drive, you install to a portable drive - maybe a USB key ring or other portable storage device.
Then whenever you plug your portable drive into a computer you can run your apps. You can carry your favorite computer programs along with all of your bookmarks, settings, email and more with you.
