Edit: Jesus Christ, people. If you buy a $150 Thinkpad made by slave labor instead of a $1,200 MacBook made by slave labor, you're still supporting a capitalist economy based on slave labor. We all do. We have no choice. The number of smug liberals in the comments saying "well I buy a cheap used laptop" or "well I buy coffee beans and make my own coffee" are completely missing the fucking point.
Don't tell yourself your consumption is moral. All of us make unethical choices every day because there is no ethical consumption under capitalism. Accept your shame and guilt and let it drive you to do better.
Also a product isn't a bad product, just because it is produced under capitalism. A computers ability to compute does not depend on its mode of production.
"It's okay to resist capitalism on an iPhone. The feudal lord who owned the pitchforks the peasants killed him with probably observed the irony too." -Ben Stiller
