offline reader?

Hello,
My work often leaves me with plenty of free time, but no net connection.

I'd like to read the net at work. Currently I sometimes open a bunch of websites and save them to my USB-iPod, then open them at work.

If there is a really easy way of configuring an offline reader I'd love it - I have to admit I only just read about portable-firefox so I hadn't thought too much about it till now.

Any thoughts are appreciated,
THANKS
Greg
ps. I use a Mac... I guess that doesn't make a difference? I can setup a PC easy enough though.
