Aos 3 -> aos 4

In my case, OS4 isnt able to do what my Classic 68k 3.9 does. For example:

I watch TV on my workbench (with OS4 I cant)
I use USB 2.0 (with OS4 I cant)
68k compatibility on 3.9 is great (whdload, demos, etc), much better than in an emulated enviroment, as everything works the way it is supposed to with no glitches.

And I dont think there is a single appealing app for PPC that is not a port of a Linux/Windows thing (better use that thing on faster x86).

Dont get me wrong, I had an AmigaOne with OS4 ages ago, and I dont regret selling it for an instant!

If your Classic Amiga has Zorro III you can get USB 2.0 with the Deneb card.  It works with the Poseidon USB stack under AmigaOS 4.0 or 4.1 Classic.

But obviously due to the limitations of Zorro III (and even worse Zorro II) you won't get anywhere near the 480Mbps of USB2 high speed.

Interesting...  but anyway, I would still loose my TV watching ability on workbench.

In the end it seems much more reasonable to me to keep using 3.9 and its many tweaks, and then use aros from time to time on my affordable x86 as my next gen Amigaish OS.
