Grudging props to Mac OS

So, Microsoft, Sony, and Apple are basically the only tech companies that I really loathe.  Microsoft and Sony are pretty much irredeemably awful.  Apple does some cool stuff (hint: not iPod) but they're surrounded by such an insufferably smug attitude and I hate the frickin' Steve Jobs personality cult.

Anyway... I'm at my grandparents' house for the weekend, and they have an iMac connected to a DSL modem.  No router.  So how the heck am I supposed to get my notebook online?
