I moved to OSX from Windows at the time of Snow Leopard. What a great operating system. I remember things "just working". I moved to an Airport Extreme to improve Wi-Fi connectivity for my Apple computers and devices, and found even more stability. After each upgrade since, I have found the opposite to be true, now things are not working very well. More complex, more bloated, to add all those features that are called progress. Printers lost on the home network, repeated logins to iTunes, even when already logged in, annoying authorization popups even when authorized, renaming my computer randomly, and other "bugs" and failures. Now, this is a matter of opinion, to add insult to injury, the interface is getting so ugly and un-user friendly. For the first time in many years, I am starting to consider other alternatives. Apple, you are letting me down. Only the die-hard Apple fans, who accept everything like it was religion, seem to keep things going.
