For me as a Gamer the Minimig core seems like the future. My 4MB Minimig with ARM addon board allows me to play all my favourite A500 games either from ADF images or using a WHDLoad install on its hard file and just works and gives me support for using a modern monitor while freeing me from using my failing floppy disks and classic Amiga hardware.
Sadly I can no longer say the same thing for my Classic Amiga's that all seem to be showing their age with failing hardware lately.
Thats not so say my classics cant be fixed I am sure a skilled tech could replace the failed caps and get my sound back on my wedge and A1200 tower. I just dont have the to keep swapping out old parts as they fail to have the same think happen 6 Months later again.
WinUAE, AROS, OS4 and MorphOS also all have their place and I am also a happy Sam440ep owner used manly for running the non games software I used to run on my BlizzardPPC A1200 Tower and use WinUAE quite a bit testing and transfering software and games on to my Minimig.
I even see a place for AROS in the Amiga's future thanks to AROS-m68k and look forward to running it on my Minimig or maybe a FPGA Replay board sometime in the future.
