I've only had my Nexus 7 since spring this year. There have been two updates, and both of them made my device faster, which was a refreshing change after having three iOS devices where OS upgrades made the devices slower, and in two of the cases, unusable.
While I'm more curious about WP8 to replace my iPhone 4, I have no issue with upgrading to an Android Nexus phone, given my experience with a Nexus tablet.
