You are “bored” with Windows. Microsoft spends over four years inventing something entirely new. In less than twelve hours you rated it awful. You buy OSX which works just like Windows used to be, a desktop with icons. How bored you will be… Of course not, not really, because it’s called something different, made by a different company, based on Unix and I hear it’s good, very good.
The bottom line is, Apple make devices for consumers. MacOS used to be the top of the line OS, but Apple really did blow it, and now they run Unix with audio and graphics like any other computer. (There are several links in this regard and to comparisons on audio applications between OSX and other OS’s on this forum, if there is an interest.)
Microsoft makes software and hardware more for technical people. Windows 8 is their attempt to ingrain a consumer (a 'la Apple) centric interface into Windows, and people don’t understand the change because they didn’t have a choice. Therefor the entire Windows 8 experience it is awful, even though there (essentially) is a Windows 7 under the hood. (A perfectly natural reaction to change.)
Now, people can argue all day long, but in the end it comes down to one thing.
