Can anyone who knows hardware estimate if you will be able to play new releases on this and how long of a lifespan I can expect? Is it comparable to a console/handheld where I'm able to play every new released game for the next 5-7 years or will it be too weak to play new games in two years time? Really love the concept but I can't justify spending that amount of money if I realistically need to replace it in two years or something like that.
I've only spent a few hours with it, but if your happy to lower settings and stick to 30fps on the big titles then it's likely fine for a good while. I'm really impressed with it so far.
I've run older stuff and newer stuff, and almost all has gone really well - even games listed as unsupported work fine. Only issue so far was Monkey Island 2, listed as supported, but doesn't work for me. The controls are borked and loading different profiles doesn't fix it.
I've tried the following 'bigger' games so far, all at 800p (native res):
Elden Ring - settings on high (whatever one level under max is), is an 'Elden Ring' solid 30fps. It looks really good too, and weirdly doesn't feel like 30fps too much.
Cyberpunk 2077 - High settings (apart from screen space reflections, they were on low - there's hardly any difference in quality) is around 30. Dips in busy areas, but you can turn crowds down a bit amongst other things for cheap gains.
FInal Fantasy XIII - technically not supported, runs fine with a few stutters upon new areas/visuals at locked 30. XIII-2 is a horrible stuttery mess though.
God of War - solid 30 at 'original' console settings, looks great and feels good to play. The game defaulted to higher settings than this, and I had a few dips, but you could certainly up some stuff with no issues.
Horizon Zero Dawn - Only ran the bench at high settings, and it's a bit juddery but mainly around 30. With tweaking should be fine.
Guardians of the Galaxy - Mainly high/max settings is solid 30 in the opening world.
I don't think you're going to be running these kind of titles at 60, even with everything lowered to the minimum quality settings, so if that's a dealbreaker it's likely not for you but older games can run at 60. It hurts battery badly though.
Quick note on loading times: I only got the basic one, but loading from SD cards is pretty quick (using Sandisk Extreme Pros, I'm going to try my old Switch micro SD later as it's rated much slower). Elden Ring loading time seems comparable to running off an M2, which is weird, for example. Outliers were the two Sony titles, both took a while to load. Nothing horrendous, but noticeable longer than the other stuff I've tried.
The other thing is, if you're thinking of getting one to replace or even be your PC for gaming, you need to factor in the storage limitations, battery life and so on. Fast Micro SD cards are around 100euro on offer for 512gb. Terabyte cards are still expensive (two 512s is considerably cheaper). Then you're probably going to want a power bank, rated at at least 45W so you can charge and play simultaneously. Another 100 euro or so.
