This definitely feels like a big part of it. This morning I was trying to look up something on my Note. I started typing in the phrase I was searching for into the search field in Dolphin, but I had to look up a model number in another app, so I briefly switched away, looked up the number and switched back only to find that I had to retype the first part of the string again. Did the OS decide to shut down the browser that I'd just been using to save system resources, or was there something else going on? I don't even know the answer, but I know that little things like that seem to happen all the time, and so the devices just don't seem to lend themselves well to easy multitasking.
