I never understand these "more RAM" posts. What is it that you are doing that leads you to believe that you need more RAM in your devices?
Safari
constantly reloads tabs - even when I'm only switching back and forth between two - or it crashes because it is out of memory.
Moving to 64-bit means that the iPad Air has less available memory for applications than the iPad 4 before it. (64-bit uses approximately 25% more memory)
I find myself using the iPad a lot less frequently now, since the browsing experience is so poor.
Another issue is that applications are basically never in memory when switching now, so it's very slow to respond when swiping between apps.
My wife's ipad mini has 512MB of Ram. It runs IOS 7 and never has any low memory anything. Has all apps opened all the time.
It's also a 32-bit device drawing a quarter the resolution of the iPad Air.
Your crashes have to do with 64bit and iOS 7, not ram.
iOS does not gracefully handle running out of memory. Instead of doing things like paging to disk, when you run out of RAM the app just crashes.
The Tab reloads have nothing to do with ram.
Tabs reload. Even with 100GB of ram they will reload.
It is both a software issue, and a RAM issue.
Software: rather than clearing the contents from RAM, they should be saved to flash so that the tab can be "resumed" rather than reloaded.
RAM: More RAM would prevent the tabs being dumped out of memory in the first place.
What is wrong with a laminated display?
The problem is that the current display is
not laminated.
Most other tablets are these days. It greatly reduces reflections/glare, increases contrast, and would stop the iPad Air from feeling "hollow" due to the thin glass. (compared to previous models)
