I'm looking for an Android tablet to replace my Asus TF101, which has been a robust tablet for a few years but has gotten intolerably slow. I would use it for:
 - Reading RSS feeds while I'm watching TV at home
 - Perhaps as a remote desktop client for my Windows PC, or as an ssh terminal with a keyboard
 - Note that I use a kindle for reading, so that's not an intended use

Here's what I'm generally looking for:
 - Reasonable quality, though it will rarely if ever leave the house, so protection and drop resistance is irrelevant. Gorilla glass isn't important for example.
 - A reasonable chance it will get Android upgrades (OEM or custom ROM), though it's not a deal breaker if it doesn't
 - Android 5+ preferred (no Apple devices please)
 - No slower than my Samsung S4 phone
 - Charge from standard USB, not like the TF101 which has a custom charger
 - 9-10" screen (9" is my minimum, 10" strongly preferred)
 - Support use of a keyboard. If it can physically connect to work like a little laptop that's a bonus
 - Budget, NZ$500 absolute max, prefer quite a bit less, even if that means using a less known brand
 - Storage space relatively irrelevant, I use them as a dumb terminal

I note that the Google Nexus 9 is currently US$300/NZ$450 from Amazon. It has a keyboard that costs US$150, or you can get a more generic bluetooth keyboard for $50. That would meet most of my requirements, but interested to see if there's something a bit cheaper available.
