Next time you are visiting the Dell or Sony website, configure one of their PC's and notice how they charge you extra to get the "Mac Like" experience, example, a clean desktop with no crapware.
Dell? Hmmm Just bought 2 XPS dells and wasn't charged extra not to get software.
The dells were pretty clean. Dell's dock is extremely handy but still rely on the quick launch on the task bar.
I had 5 icons on the desktop out of box. Not sure how much cleaner it could be out of the box. My son's had 6, the extra one was for nvidia sli
You can run a dell with windows only, no special OEM drivers or software required. sony and HP I don't think that is possible
In the past I used to reformat all my dells and perform a fresh install to rid all the crap. this time around I am still running on the factory HDD load
