WebWorkerDaily shares their top-ten list of portable apps and for those on the run, this is a good set of tools. By portable, they mean applications that can be run off of an external USB drive, like a thumb-drive. There’s a few advantages here, the main two being that you can run the apps you want on practically any PC you come across and the fact that your private data stays with you. You won’t leave traces behind if you’re surfing in a web browser that’s running on the USB drive you’ll take away when you leave the PC.So what’s on WWD’s list? The apps range from graphics utilities to e-mail clients like Qm (shown) to VoIP applications and everything in between. Several, like IrfanView and Miranda, I’d heard of or used before. Others seem a little more esoteric to me, but all in all a good list worth reviewing. Hey… where’s portable FireFox, which is a perrenial fave? What other portable apps are you using that feel are list-worthy?
