Is the only 1GB of RAM in iPad Air preventing you from purchase?

Hey guys-

I had plans on buying an iPad Air for the holidays, but I'm seeing a tiny bit of chatters on our forums and elsewhere about people being prudent, since it only has 1GB of RAM. I wouldn't want to shell millions of dollars (well not really but you get the point) on a 128GB iPad Air (over $1000 with tax), only that it would become useless in 1-2 years with new iOS updates i.e. iOS8, iOS9.

If I make the dive into a tablet purchase, I want it to last a while. If not, then maybe I should just buy an iPad Mini Retina 16GB for $400, and only install 10 apps. At least then, I won't be losing as much money every 1-2 years.
