yes, hundreds of them, all shapes n sizes.

do not buy one and ask yr mum to get in with it!

try it YOURSELF first. then u know if it will be suitable for older people.

go visit the shops and IT malls, ask, see demo.
4mb is on the low side but can get SD stuff.

hk tvb can get but may be limited, may not be very reliable.
sony smart tv - has it got google android tv, hv u have installed apps n working?

if yes, u can try it there first, like a box.

if no, it is of no use, get a separate box.

an android box is not the easiest device to use in terms of free entertainment.

so, there is a need for the user to learn how to find, install and maintain the apps. most of these free entertainment apps are not found in playstore. interest, time, a learning process is required. if not, it will be a very frustrating experience.

"HK tvb drama" can be found in a variety of ways - some on live HK tv stations, some on video on demand with certain apps, some via websites or youtube, some as an addon in KODI app. they come in a variety of quality, reliability and selection. it will take the individual to decide what is good and what is not good.

as i do not watch HK TVB drama much, i can't comment further on the details.

yes, get 2/16 android 5 or higher. 2/8 might be OK if limited usage.

remember get an simple air mouse too.

Kodi add-on like Icdrama and Azdrama or app like Kakoze Drama is good enough for TVB series. I'm a TVB addict by the way.

Yes, upgrade to 8mbps will surely give better performance.

Maintenance means...

.. many apps or addons in kodi decay or die over time, not auto update. Because they owned and provided by their owners. It depends how well the owners maintain and if they are not harassed, blocked or shut down by regulators. If an app dies, u need to find install new direct replacement or similar. Since they are free, cannot expect all to be well n good all the time. But over time, a user will learn how to keep up and get enough to watch.

.. box firmware updates.. how to get varies from box to box, brand to brand. Some can get online, some can get from sellers. Do consider this bit when buying a box.
