I think truthfully in MorphOS,there is a lack of modern native apps, but you can run any classic amiga system friendly apps. (there is alot more than you think) MorphOS does also have the best modern browser.
You can also run anything amiga via emulation, I hear it can handle most things. (games, demos etc very well even on 1.0ghz range hardware)
Is there dosbox for morphos? I think so and so there is tens of thousands of dos games and apps there to run on your system.
There is a c64 emulator also if your really a commodore fan.
I think you'll always need a windows computer for work/school/whatever, but its nice to have a fun computer next to it for games, creative projects, and more.
I'd like a mac mini for this and morphOS - someday... But I've been saying someday for awhile.
All Amiga next gen OS systems really need 1) Audio editors, multimedia rippers, converters, 2) Video editing programs 3) Games that are not just linux ports
4) Productivity apps (office, pdf writer, budget,spreadsheet, more) 5) More creative apps
like 3d font renderers, web editors, animation programs, ray tracing, and more.
Of course, linux also needs many of these things, but to a lesser extent, I guess because its been around long enough to reach a level of maturity of apps available. I hope All next
gen systems will continue to mature with more to offer.
There is a big move on linux right now of games games games now, its nice to see.
Weaknesses of a system getting addressed is always cool to see. I hope there will be more amiga next gen apps and games. Limited budgets, limited developers, its not a good
environment or atmosphere to encourage development.
