Wait Until You've Done Some Research
Make sure you do your homework before you commit to the Galaxy Tab S6.
There are plenty of other capable tablets on the market right now including the Galaxy Tab S4 which, again, got upgraded to Android Pie and Samsung's One UI and is cheaper than the Galaxy Tab S6.
Samsung's also released a Galaxy Tab S5e and it's worth a look if you're committed to buying a Galaxy tablet.
If you aren’t married to buying a Samsung tablet, you should take a look at Apple’s iPad line. Apple’s iPad Pro lineup, iPad Air, iPad mini, and iPad models are solid Galaxy Tab alternatives and all of them have been upgraded to iPadOS 13.
You should also make sure to look at the best tablet alternatives running Windows 10 which includes Microsoft's Surface.
Be sure to go hands-on with these tablets before you settle on buying the Galaxy Tab S6. If you find a tablet that suits your needs, don’t be afraid to make a move.
You'll also want to access your storage needs (128GB vs. 256GB) and decide if you'll need LTE connectivity.
