Really all depends on what you want/need to do with a tablet or computer.
At home, all o use is my iPad anymore. There’s an app for almost any task you need to accomplish. And most productivity software has some sort of companion app. Microsoft 365 allows me to connect into any of the Office Suite apps. The Adobe suite allows me to work on my Photoshop or Illustrator projects right from my couch. And I can upload, download everything to my team members right from the couch.
But after work, I’m just surfing the web, scheduling personal email, scrolling social media, on Amazon, or streaming Netflix or Spotify. I’m not doing any heavy lifting that I need a computer for, and am not storing large files that I can’t use a cloud service for. I’ve got a BT keyboard for it that works just fine, and I can access all of Google’s Office-like apps for free if I need a word processor, spreadsheet, mail, or whatever. And like I said before, almost anything you want or need to do in your personal life… there’s an app for that, so there’s really not too much the average home user can’t do on a tablet (Apple or Android)
As for ecosystems, this is all really a personal matter and what works best for you. As a designer, I’ve been embedded in Apple stuff since the mid-90s - before tablets, smartphones, the cloud, or even truly capable laptops. So the ecosystem works for me, because I can seamlessly connect all my devises at will, hand-off files from one to the other, sync reminders, or whatever. But what works for me and my situation may not work for you. And honestly, with a little work, you can devices in multiple systems to all play nice together.
Really, once you figure out what you use the device for on a daily basis, you can go from there. All the options have some pros and cons. But all can absolutely work as the only devise with some few minor workarounds based on your individual needs.
