It's a couple of months since I last had visited the portable Apps site. They have added a whole raft of extra applications since then.
It is reaching a point where, if you have a big USB stick drive (and £4GB ones are now on sale at less than £20 on the high street - about £7 on Ebay, with 8GB ones now dropping in price), you can run something that does the same basic job as almost anything you would use the big computer for.
It also means you can carry the files you are working on, and continue your work using almost any PC with a USB connection.
Quack!
