the Original Amiga Desktop - is so... well 'old' compared to almost anything by todays standards. :) Get an Amiga Emulator going and try out the various Work Bench versions and see. You likely will find the desktop very unusable by modern standards.
Of course people really dont use amigas (much) for real work these days - its all about the games. Or just to play with an Old OS.
Something i have on order - an Amiga 500 'mini' (basically a SBC running an amiga emulator (or something)) I dont have it yet. I tend to just collect these fun things.
You can add your own games to it as well:

"Side-load your own games via USB stick with full WHDLoad support and an array of options to choose from - plus, save and resume your game at any time to help you finish those punishingly difficult classics
The A500 Mini is compatible with 100s of classic Amiga games and demos, utilising WHDLoad for simplicity (games must be legally obtained/purchased from the legal owners), 50/60Hz in 720p HD via HDMI, Multiple scaling options & CRT filter"
Unfortunately, i didn't see anything about storage size and how many games you can load. You might have to keep a spare USB flash drive plugged in to store them!
