For my Android development needs, I'm not going to buy the Samsung tablet anytime soon, although, for development purposes it would be nice to have a big screen as my app can use a lot of real estate.
If I were to get it for personal use (not development), then, for me, the screen resolution's a bit low, they use USB 2 instead of 3, I'd also want an HDMI output port (didn't see one listed), a wired ETH port, and the ability to plug in external USB drives to read/write content. I don't need the stylus. I didn't check out the adequacy of the included sensors, and being able to plug in an external, high-quality mic would be nice.
Currently, I'm fairly happy with my Nexus7 as a development platform.
