Yes, but it is the Internet. Thus, you must have a car analogy.
Your 1993 Escort Wagon is a fun example. It's got some extra room for carrying grass seed or lots of groceries. It gets good gas mileage. As a 1993 vehicle, it probably produces more smog than a newer vehicle. It has no torque, so you don't want tow anything uphill with it.
But it hits a certain sweet spot--it does everything you want a car to do.
By your original statement, I would have one car for going fast. I would have another car for carrying groceries. I would have a third car for towing a boat or carrying heavy things. Realstically, that's not going to happen because cars are too expensive.
But do I want four different devices? Do I want desktop with a nice big screen and high-performance for working at home, a laptop for working on the go, a tablet for light-tasks while I sit on the couch, and a phone for when I'm out and about? A company like Apple, of course, says that's exactly what I want and they are more than willing to sell me each of those devices.
What Microsoft is trying to do is find that sweet spot that, in a car, is filled by your 1993 Escort Wagon. Something that will satisfy the largest number of people. A jack of all trades and a master of none, if you will.
