The whole modern computing experience is bloated:
Ten years ago, I gathered information from the internet (usenet, hotline, web), wrote essays in a text editor, managed files, burned CDs, played the odd game, did a bit of programming, etc. etc., on a 603e based Mac with, I dunno, 32? 64? megabytes of RAM. It was fine, quite snappy except for the modem speeds, all in all a thoroughly enjoyable experience when you kept the system clean (plus, OS8 was so beautiful).
Today, I struggle to perform those exact same tasks on a Mac that's an order of magnitude faster and has 10x the amount of RAM - because these tasks are now much more complex. I of course know that rendering a complex HTML+CSS+JavaScript web page is more intensive than HTML1, but I don't care. I just want the information on it. I know that all the layers of abstraction present in a Mac means that each application will take up more resources, but, really, I don't care, I just want to type text. I am doing the exact same things I was 10 years ago, but now I've got swapping left, right and centre because I don't have a full gig of RAM, my operating system takes up 5 gigabytes on disk and my 1.33GHz G4 can be brought to its kness by a web site - which I'm BTW *still* waiting on cos site sizes have multiplied seemingly faster than download speeds.
So: hardware's got faster, I've got RAM and disk space in abundance, but the experience is *slower* and less responsive than it used to be. I think that matches a dictionary definition of bloat, if there is one.
As for Macs 'just working', of course it's not true all the time. Just like what we used to say about PCs - 'it just doesn't work' - isn't *always* true (but quite often)
