Oh I do t remember you saying anything about the note 2. I think it is very close to being as smooth. I am fine with throwing the iPhone 4 out, but I was proving a point. You still have yet to saying anything about the iPad mini and the nexus 4. You can say whatever you want, but if you want to compare different devices on each OS then the iPad mini has to be listed. It can't keep up with any of the other devices.
I was just saying the example of the N7 versus the ip5 because I've owned both devices and the N7 is quite beefy in terms of specs, it's not very far off from the N4, I'm not sure why it matters that it's a tablet, but I understand you want to compare the N4, unfortunately I've never used the N4 so can't make a judgement. I only had an ipad mini for a couple of days, and yeah I'll agree with you it is sucky, all of the ipads I've had have been pretty bad for memory management, they were not laggy though, but they crashed a lot especially with a lot of browser windows open. I'm the wrong guy though as I switched off ipads a long time ago and now enjoy windows tablets which are much better than either ios or android IMO.
I'm sure the N4 is nice and smooth, until the battery runs out!! Hehe I'm just poking at you.
