iPads are made for a lot more than that but as a desktop replacement? No, the format does not lend itself to that. Even if we had feature parity in apps, most will want to have a larger screen to use it as a desktop replacements. External screen keyboard and trackpad sounds like a Mac is a better choice.
Furthermore, you, like me, probably are well entrenched in keyboard and mouse/trackpad operations and therefore have a deep preference for that so even if had app feature parity, we could likely gravitate towards traditional "computers". We are biased. It is much more interesting to get the views of people who have not touched windows of MacOS.
