With all this talk about the Air only having 1GB, do *you* really see a noticeable affect from this? So many seem to talk about numerous tabs always open, etc. but is that really a typical situation you find yourself in often? I typically have one, maybe two open at once. I will say this a recreational device for me, not for work or production of any kind. I never go in and close apps in the background and I have yet to experience any type of lag issues. Either way, I'm beyond happy with this and it's a pretty big improvement over the Mini I had. Maybe it's not a huge leap from the 4th Gen but it seems great to me overall.
