I have video proof, and because you can't recreate it in you testing, it's not a problem, and my argument is invalid.
Gotcha.
In my case, no I don't think the RAM issue is very severe since that scenario worked fine for me, but like I said that's on my iPad 3 without Gaussian blur. Maybe it is an iPad Air/full iOS7 problem. Maybe the Air did need to ship with 2GB, but it didn't.
So in the meantime, iPads will refresh when it runs out of memory (and will still refresh even with 2GB if there are enough tabs open), that's just how Apple designed iOS to work.
EDIT: I want to clarify that I didn't buy the iPad Air mainly because it didn't come with 2gb. I'm fully aware of how stingy Apple is with their RAM. (They're still shipping the MBA's with 4gb by default for example...) That's just how the company operates, always putting in "just enough". People will buy it regardless, because new and shiny, and because the majority simply don't need that much RAM. Their answer to those that do need it is expensive BTO options.
If we want to see a possible trend that could be coming for phones/tablets, look to the LG G3, which is shipping in 2 configurations: 16GB/2GB ram and 32GB/3GB ram. If Apple were to do the same, they could put 2GB in the 128GB only version. I seriously hope they don't this, because if they do, we will likely whine about it on the forums for awhile, then break down and buy it in the end <_<
