Tech press haven't realized that not all the Nexus devices get updated
I keep hearing people say to get a Nexus if you want all the latest updates. That hasn't been true for awhile. The Nexus One has been completely left behind. The Nexus S doesn't get the latest updates OTA for weeks (timetable is similar to skinned devices). The Xoom takes awhile to get updates. The Gnex on Verizon gets updates months after the update is released.
The only way to really get updates is to learn how to root and rom your phone. Get the phone you want and don't worry about updates. It doesn't really add that much functionality and if you hate the skin that you are using then just download a launcher. There is a reason why most launchers have millions of downloads.
