Very amusing that you think that as that approach is what got us into this mess. MS (not to single anyone out in particular) has always been notorious for rushing a buggy 1.0 to market then iterating it. That's why you need a quad-core 3Ghz PC with 8G RAM to write a single page of A4 now.
I can't agree that a buggy and slow version of a product is an MVP.
There are a lot of things that you can cut from a product to make it minimal. I don't believe quality is one of them.
However, I also believe that user feedback cannot be the only factor to build something truly great.
Point taken, though I meant minimal feature set, not buggy. Also, 2000 and later Office and Windows are hardly the worst offenders in terms of "software that sucks"
