My most used tablets are from 2011 and 2012. Galaxy Tab 2 10.1 and 7.0, Galaxy Note 10.1, Galaxy Note 8.0 LTE, (2012) and VisualLand 7" tablet (2011)
They're too old to get OS updates anyway and they're stuck in skeuomorphic land which is why I bought them. That's why I see lack of updates on Android as a feature and not a bug. They can't be flattened. But yes, you can downgrade the OS if you know root, and can even install unsupported builds (newer versions of Android, custom ROMs) and to an extent, even full mobile Linux. Try that with an iPad! Once I found out the hard way I couldn't undo iOS 7 on my iPad 3, I was done.
Recently I tried Apple again, with an iPad 6th Generation, and it's a nice enough device, but with 90% of my purchased games and apps not compatible due to losing 32-bit support, it makes me question 64-bit's purpose other than breaking a lot of excellent apps and games I loved that actually ran better on Apple hardware. So now if I want to play them again (the weren't made available on Android) I have to scour the internet for an old iPad 1 or 2, hoping they didn't get iOS 9, or 7, and retry the download/install. I can't find iPads that old yet. I'm still looking...
If Microsoft and Android can offer backward compatibility with 32-bit apps, why can't Apple? Darnit I hate futurists.
FYI the 'reloading' thing isn't due to RAM on Apple stuff. It's because even today iPads and iPhones don't truly multitask. They 'pause' apps in the background and they often reload or refresh on going back to them. Its jarring enough to be annoying. I remember when Android did that way way back in the 2.2/2.3 days because of RAM limits, but with Apple it's a feature, not a bug.
