So far, my iPad air has been working great with the things I've done with it. There are some threads on other forums where the 1GB of RAM keeps coming up as a potential problem. Safari can only have so many tabs open at once and then frequent reloading starts. Some people see several low memory errors in their diagnostic logs. The 64 bit architecture apparently uses more RAM so that leaves less for apps. I realize that everyone's usage is different and many won't notice this. I just wonder if it's a concern going forward though as more and more new apps come out that will take advantage of the architecture updates. I do wish Apple would have went with 2GB of RAM but I'm sure that would have forced them to compromise on weight or some other design factor. Thoughts?
