I've only used them as keyboards, so I'm not very familiar with the media controller options, but as far as I can see it's a very easy mode to use.
You can use two of them at the same time, one in each hand, but it probably won't be necessary, you can get to type very fast with one hand.
They are very well supported on iOS. I once plugged one into Windows and it seemed to work fine, but I have not tested it extensively.
There is some room for improvement, but it really works, flawlessly [3].

Something as simple as a few bans or sanctions are more than enough to stop you, for example, from using your credit cards to pay for everything you take for granted, call it Netflix, iCloud or even a $0.99 app. And that's just the tip of the iceberg.
My advice on this? Be a pragmatic fuck. For example:
#1 Switch to open source or at least free alternatives for everything you can. #2 If you see it coming, temporarily suspend your "good citizen" behaviour and pirate what can't be solved with #1. (assume the risks and learn to deal with them). #3 Stay as local - your house local, not your country/union local - as possible, avoid "the cloud" if possible or create your own if it makes sense for you, a homelab or whatever. #4 Stay as anonymous and low profile as you can; even if you support your government in a conflict situation, they can turn on you in a blink, for the right or wrong reasons. #5 Familiarise yourself with things like Tor, VPNs and anything else that can help you bypass censorship and access blocked sites and services. #6 Consider having additional ISPs as failover options, something as different as possible from your main ISP. #7 Buy stuff to protect your electrical equipment: regulators, protectors, UPS and so on.
I'm not saying you have to do it all, take only what makes sense for you, but keep an open mind and consider that permanent peace and stability could be your lifelong situation if you are lucky, but maybe not. Says the guy who had it.
Trust me on this, I have become something of a cheap prepper, and not because of a war, it's far from that in here; just a few disagreements between governments, a few nationwide bans/prohibitions/sanctions, or a little bit of government incompetence/stupidity, are all you need to start having problems with international payments, problems accessing certain websites and services, problems with your Internet access, and even power outages, it doesn't take too much to start having a shitty digital life.
The future promised in Star Trek and even Apple's Knowledge Navigator [2] from 1987 still feels distant. In those visions, users simply asked questions and received reliable answers - nobody had to fact-check the answers ever.
Combining two broken systems - compromised search engines and unreliable LLMs - seems unlikely to yield that vision. Legacy, ad-based search, has devolved into a wasteland of misaligned incentives, conflict of interest and prolifirated the web full of content farms optimized for ads and algos instead of humans.
Path forward requires solving the core challenge: actually surfacing the content people want to see, not what intermiediaries want them to see - which means a different business model in seach, where there are no intermediaries. I do not see a way around this. Advancing models without advancing search is like having a michelin star chef work with spoiled ingredients.
I am cautiously optimistic we will eventually get there, but boy, we will need a fundamentally different setup in terms of incentives involved in information consumption, both in tech and society.
Everything there is in Spanish EXCEPT for an (fictional?) idea to replace Google with a decentralized alternative: https://cipr.info
There are also "air gestures" (Smart TV control, air mouse, and media control modes) that don't require a surface. (By the way, there are recent updates in this department that leave out the Tap Strap).
I'm not into gaming, VR sets or the like at all, so I can't say how good or bad these are for that sort of thing, but that market seems to be the main focus and direction the company is taking these days.
