Tiger Vs. Longhorn

Excellently put by Jo Miller

Big Cat
Independent hunter, sleek, fast, and powerful. Typically found roaming the jungle. Self-cleaning, likes to play. Beautiful and endangered.

Steer
Enslaved overfed ruminant miserably awaiting slaughter. Typically found in pens and abbatoirs. Swats flies with tail, requires antibiotics. Ungainly and near-ubiquitous.

And here's something else I saw today, in the print edition of MacWorld magazine that just arrived, that demonstrates how creative, funny and just plain cool Macs and Mac users are: the Big Tiki Drive.
