So I made this as a throw away comment on this thread:
You'll use your relatively cheap device to connect to a remote desktop via the 200+mbps connection. The remote desktop will be an i3 for $15/month, i5 for $20/month or an i7 for $30 month. They won't wave goodbye to profits.
I started to think about the nuts and bolts of it all. Thinking about how things are marketed, thinking about the technical ways of doing it. Here's my pitch...
Using Office365 as a model. It is sold as always updated, always secure blah blah blah. Of course having a remote computer can easily be sold this way....
"Do you want a computer that is always updated, always secure? With the latest software updates always ready. Performance when you need it, where you need it? The Remote PC 3000 is for you!"
How would it work? Puppy is perfect for it. Obviously Windows is the dominant player. But, windows only works on the device it was installed on. Windows is big and heavy. Windows... well we all here know about windows.
Sell the end user storage, that's their save file. 50gig chunks. $2 / month per 50gig. All backed up in our safe and secure data centres.
Oh, you want to use your save file? No problem, $15 / month for the i3. You can check emails, check facebook, find cat videos, do word processing and spreadsheets. You know, the basics.
A few months in, you realise the i3 isn't going to cut it any more. You need more herbs. Swing us an extra $5 / month to upgrade your PC. If you're from the windows world, bugger. You can't just easily do that. Yay for puppy. The i5 in the data centre spools up, loads your save file and voila, same set up, new machine. All for only $5 more per month (enter the promo code for 6 months free upgrade to i5).
What's that? You want to play games? (assuming WINE works great) No problems. Give us $30 per month and you can run on one of our i7 machines with 32gig RAM and NVIDIA 3080Ti. Oh, your game needs an update. It's 50gig. No problems, just buy another data block or 3, only another $2 /month each.
All of this is of course available on your "dumb" terminal. Smart TV, Smart Phone. Low end PC. IOT Fridge. Whatever can connect you to the internet can connect you to your Remote PC 3000 via VNC with end to end encryption...
