i don't care what any windows OR mac user says windows antivirus is subpar although much more effective than mac os. the two can't seem to stop steaming ideas from each other, and neither of them make very good mobile devices. mac is an old unix distribution from like 10 years ago that they are making progressively shinier. either way windows is like an overbearing parent and mac is like hiring a hot prostitute to do your math for you. don't let mac os steal from the amazing ideas of unix and linux any longer. we have 3 million users and counting and yet nobody can wrap their head around the idea that linux isn't some complicated mess of code that all the illegal hackers use. YOUR ANDROID PHONE RUNS A LINUX KERNEL. (the linux kernel is like the software processor on windows or mac, it is what makes it run) even macs can't disguise the unix kernel they run. stop the theft. use linux. i promise you won't be disapointed.
