Yeah, I own plenty of computers, including a 2009 macbook that was purchased new, and run a repair business. I still wouldn't waste another cent on apple products.
If you:
a) Are a faggot and/or a hipster
b) Have no desire to ever manually upgrade or replace any component, including the battery, or even open the case
c) Don't mind paying a premium for 'high end' hardware that's often close to a year behind every PC manufacturer
d) Can deal with the fact that a T540 is 10x the machine for less money, and just want a shiny status symbol with a big apple logo on the case
Then by all means, buy a Mac. Do it faggot, then kill yourself.
