They didn't, Google are the first to do three years of OS updates and security patches with the Pixel 2 and extended that to the first gen Pixel. Samsung were doing two OS updates until they promised they would do 3 OS updates at the Note20 launch and extended it to the S10 and other models. You are correct that they upgraded that to four with the S21 before Google made the jump from 3 to 7.
It was comparable in price to the Edge 40 in India which was the only market it was launched in at the time of the comment. The European price is over the top but it should probably get price cuts soon.
A hands-on article from the same website says it's not pure wood. It's been treated to protect it from water and skin oil
There were rumours about "Dream Chip" i.e. Samsung Mobile designing their own chip. Exynos is designed by Samsung LSI, they're part of the same conglomerate but there is a lot of internal competition apparently. Might explain why the Samsung OLED panel on iPhones is sometimes ahead of the Samsung OLED panel on Samsung flagships.
True, although you'd have to pay quite a bit extra to get 7 years of updates as this phone is half the MSRP of a Pixel 8. The 7a is a year old now so it'll likely only get two more years of OS updates and four years of security patches. Tbf it is good Nothing are providing 3 updates since the phone is $300 in India and €349 in Europe. The Poco X6 Pro matches the update commitment but MIUI had a reputation for being buggy outside China. HyperOS (MIUI's successor) also has ads in system apps and a lot of pre-loaded bloatware. It does have a faster chip and storage compared to the Phone 2a though so there are pros and cons to both devices.
It might not be powerful enough to run the software longer and the hardware may show it's age. Secondly the cost of the phone cannot be ignored either, more software updates means more money spent on software development. Android updates have to be certified by Google. This process costs money. It isn't feasible to expect a company to provide more than 4-5 years of updates at that price point unless they start charging for updates or make money through services or ads.
I don't know if the hardware will be good enough in 4 years anyways. They've cut corners to get to that price point, the chip is similar to the 778G from 3 years back and it's using UFS 2.2. Honestly the phone feels like it was made for India and the marketing indicates that. They don't have many options with a clean OS and 3 years of OS updates at that price point there.
All Sony phones (including their flagships) get two years of OS updates and three years of security patches. That's rumoured to change this year but the Xperia 1 III and 5 III are not getting Android 14.
It costs less than any of Apple or Google's offerings and they do not make money through software and services unlike Apple or Google. I think it's unreasonable to expect 7 years or more of OS updates on a phone that costs $300-400. They should do better on their flagship though, it costs double but still has the same support.
This phone is 72.4 mm wide according to GSMarena. Height might still be an issue for you since it's 161.2 mm
Tbf it is cheaper than the Edge 40 Pro, they messed up their naming. This phone is the successor to the Edge 40 not the Pro. Mind you there are still some downgrades as they downgraded the storage to UFS 2.2.
And will still have that awful GN3 sensor on the primary rear camera. Xiaomi were using a Sony sensor of the same size on the Redmi Note 12 Pro a phone that cost somewhere around $200-300 depending on the region it was sold back in 2022 and 2023.
