Question When choosing an inexpensive Android tablet...

[golem]

I'll start by saying I'm a bit weird -- Have built my own PCs for 25+ years but never forayed into other devices, still using a Lumia Windows phone from 2014. I'm finally needing an android device for occasional Bluetooth/WiFi duties such as connecting endoscopes, MP3 serving to amps, televisits, picture documentation, etc. Currently looking at 9"-11" tablets in the $100 or less range. My question is what should I be looking for or, in particular, looking to stay away from in regards to hardware (CPU, GPU, display, etc.).

Any insight would be greatly appreciated.

How well the tablet suits your needs and expectations.

or, in particular, looking to stay away from in regards to hardware (CPU, GPU, display, etc.).

With tablets, there's little, if any, option regarding hardware. Best bet is reading reviews, to get a sense how they fare.

However, do note that when you pay peanuts - you will get monkeys. So, cheap tablets (all hardware in that matter), have several cons. Up to you to decide if you can live with the cons those cheap tablets have or not. If not, better look towards mid- or high-range, which are built better with less (or no) faults.
