I already named Dell. I agree that corporations tend to make political donations to the powers that be.
Having someone like Al Gore sitting on your Board of Directors is a different proposition, IMHO. You're free to disagree, and even to argue that he's a wonderful guy and you love having him there, if you wish.
I’ll just stick with the hardware/software in front of me on a daily basis (Dell-Windows/Apple-OSx), and say I’d rather have the Apple any day. I’m not going to buy crap, for something as essential to my every day life as a computer, just because the guy who runs the company gives to one party or another.
