Yeah they do on the A8X, but only after you open about 15 tabs, lol. I know because I have an iPad Air 2. And that is the #1 reason I want to upgrade. My 6 Plus is so bad that it cannot keep more than one tab in memory. Sometimes just loading a single page causes crashing. Or opening a single page and clicking the button to view the tabs, but then going back and not opening a second tab. Yeah…it's horrible and I can't wait. But I agree the software is also to blame. Adding RAM masks the crappy software underneath—but since Apple refuses to do anything about it I'll take this "fix" for now. Here's to hoping for a re-written Safari in iOS X.isnt refresh an OS thing not ram? they still do on the air2 and that has 2GBbut A8x not 9
