This exact same conversation came up a few months ago and I was called a troll for saying that I didn't think so.
I still don't. MM is a great game, and it does everything right, but even when I was offered one for under $4k (many moons ago), I could buy 3 or 4 other machines I really wanted for the same price, and no matter how awesome MM is, it isn't better than 3 to 4 other machines.
If you don't have the space though and you got the money, sure it's worth it
