Most of these have been said before, but they probably still count because most people like them.
Apple products, especially Macs. iPhones, iPads and iPods are alright, because there isn't much you need to do on them that is productive, so you only need a simple interface. But Macs are just so impractical for getting stuff done. I also hate the fact that Apple doesn't follow the standards set by almost every other computer company, meaning if you use an apple product, almost all of your hardware and software has to be Apple as well. You also can't run .exe files on Macs, you can't buy the parts individually and build it yourself, and they are so overpriced that you are mostly just paying for the name. Also, Apple don't even use correct grammar (the first letter of the word is supposed to be a capital, not the second.)
