I have to say, I thought the Maxx had a much snappier and smoother OS and smoother overall experience. Not really sure why everyone thinks ICS is the bees knees, when side-by-side multitasking on both phones - the Maxx was obviously faster and smoother than the Nexus (maybe I have a bad Nexus though, so I don't know if this is normal).
Maxx definitely felt more solid as well, Nexus has cheaper materials and it shows. The screen on the Nexus is obviously higher resolution, but I didn't think it was that much better, if at all. For these reasons, I thought about exchanging it right then and there, but they were out of stock, so I have to wait anyway.
(surprisingly, the only thing the Nexus had on the Maxx at that store was the 4G signal speed. I would consistently get 12-16mbit on my Nexus, vs 5-10mbit on the Razr. I was quite surprised as these forums paint a completely different picture on signal strength)
One thing I forgot to check was the autorotate - which I hate on my Nexus. It's slow to respond, sometimes REALLY slow to where I just get fed up with waiting and go back to the mode I was in originally. People say this will get fixed in future updates, but who really knows for sure?
So I guess my main questions is - How is the autorotate on the Maxx? My gut says it's faster since the OS is so much smoother on the Maxx, but I totally forgot to check that feature at the store and that was a main reason I went in to look. I won't be able to go back to the store until Monday, so that's why I'm asking.
I've got a couple weeks left to decide which phone I want to settle on, and this phone will ultimately end up as my wife's as well, as I get to use her upgrade in the next few months.
