What's the real incentive to get one of these over continuing to use UAE instead?
PoV: You're a middle-aged computer toucher with too much disposable income who likes to mindlessly consume and won't use this thing for more than ten minutes before taking pictures for facebook/instagram/amiga forum and then chugging it into some corner anyways. It all makes sense then.
Get a normal PC (for PCs of the last 10-15 years emulating an Amiga with reasonable accuracy is a minor task) download that humongous TOSEC archive that fits on any cheap SSD, play til the cows come home. (and play old PC games, other platforms etc. on top) There are also ARM SBCs that can do this just fine, I personally wouldn't bother with them as x86 entry level hardware is often cheaper, more performant and more convenient. For the money that mini costs you can get a used laptop, put an Amiga sticker on it, and make a minimal Linux/FS-UAE setup that boots directly into the emulation (WB 3.x emulation with network stack and everything) and you have the most powerful Amiga ever created, keyboard and screen included. Or just do it on your regular PC you probably already have anyways.
Or put the money down on a real Amiga. I admit I don't know what the current prices are but these things don't break, the newer ones need a bit of care but the original A1000*/A2000*/A500 is indestructible. If you ever only buy one and actually intend to use it often, it's worth the price.
*after power supply maintenance. Caveats apply
Whatever you do though, get a screen that can do 50 Hz without jitter. I always thought the minor jitter of 60 Hz screens with PAL content doesn't really bother me, I was too used to it already to care much and I'm generally not the "I need 5000 FPS/0.0001 ms latency OR ITS USELESSS!!1!" type but I recently got such a screen unintentional and wow, smooth scrolling etc. in Amiga stuff is
nice. I forgot how nice. Such screens used to be hard to get (if you didn't want a CRT or TV) but nowadays any freesync compatible (which is a lot of them) screen can do it. (and it only took what.. 20 years?) A portable screen at 1080p is a perfect fit for both hardware upscalers and emulation + common Amiga resolutions and at smaller sizes of 14-15" has nice and high DPI&upscales the Image into a size that's fitting for the graphics of the period. (Never understood people who play this stuff on 50" TVs, the pixels are as big as your fist and forget about using a GUI without feeling like a retard)
