I'm going to jump to Samsung's defense here as I think your anti-consumer belief is misguided:
- the SD card has been drifting away from most Android phones for the core reason of reliability. Data stored on SD cards is not at reliable and when apps are forced to run off the SD card, there are side effects and crashes which are nightmares for devs. When a non brand SD card loses a user's data, the user blamed the phone manufacturer, which is akin to putting the wrong fuel in your car and then blaming the car manufacturer that your car won't go.
- mag-stripe. Considering they are a Korean company, I don't blame them for dropping a complex feature used by a select few in the US. Because the US is the only country left that thinks the ancient technology of the magnetic stripe is still a good medium for the transfer of your bank details. Contact-less paymemt is now pretty much standard everywhere else and is so much more secure and standardised. The range and reliability of the contact-less payment has increased massively for me on the S23 in comparison to the S20 which was also lumbered with magstipe support.
- dilution of features? Again, why should it be more complicated? A larger phone can incorporate more lenses, screen and battery, but the core features and benefits should be the same to make the choice simpler for the consumer. Advertising of the range is simpler also.
Each to their own but these are just my views based on 11 years in the mobile phone retail business.
You'll need an OTG MHL adapter that has HDMI out as well as USB for your mouse.
Hook up to a TV, and it should just work..
