That's what it's coming down to for me. Battle of the OSs AND best Specs. So ever since I've got my iphone and started realizing I may very well move on, i've been looking at reviews comparing the iPhone to other phones. But I've been only looking at Apple dedicated sites. I've decided I will definitely buy another phone come summer. ICS seems to be the real deal. After doing more reading, it seems the Galaxy Nexus is under spec'd compared to other Android phones. So if ICS works so amazing smooth and lightning quick on it, then I can't imagine how fast it will run on a phone like the high end Galaxy phones or the high end models from HTC. I'm not gonna chase specs, but I will definitely buy a Samsung or HTC running ICS come summer. I want the best hardware/software my money can buy at that point in time. These two seem to be the big boys for Android. In the meantime it's comparisons like this that encourage me more about ICS.
