I still don't see the point of tablets. It's just a smartphone with a larger screen, and practically all people already carry phones.
Might as well go for the laptop at that point given that it can actually do far more imo, unless you ditch the phone and go for one of those half phone half tablets I guess.
I'd rather watch movies, read, play certain games, etc. on my tablet than on a phone. (Obviously there are also specific use cases like digital art.) That said, I mostly use my tablet when traveling and it's a distant third in necessity compared to either a laptop or a phone--and only somewhat more useful than a smartwatch.
Watching movies on a tablet is terrible, though. All methods for propping the device up so you can watch the movie are inferior to the way a laptop screen props itself up via hinges and a base.
On a plane I'd rather use the tablet in my lap than have to put the tray table down. And in a hotel room I'm watching on the couch if there is one. (I do also have an attachment for my tablet that will let you prop it up on a table but I mostly don't use it because it adds weight.)
For reading, I'm probably bringing my Kindle along if I don't bring my tablet.
If you do not have one, buy a dock! I have a sp6 and 4 , and having the dock makes it quite the device. Speakers, multiple external monitors, keyboard, mouse -- a full desktop setup, I can grab and either stick a keyboard cover on or just use as a reading device on the couch.
Back to work? Sit on table, one cable and it's back to a desktop and charging up again.
How old are you? Because larger screens become really nice as your eyes go bad. And I don't need the full size of a laptop for things I'd want to do on a tablet.
